A downloadable game for Windows and macOS


Marina is a second-semester senior who is struggling in AP Chemistry! The dean suspended her from the water polo team until she can raise her grade. How will she change her study habits? Whom will she seek help from? Her chemistry teacher? The class T.A.? A study buddy? Will she be able to raise her grade in time for the Championships? Or will she be spending time wooing her tutor?

Thank you so much for your feedback! I'm glad you like the story and the characters and that you find the MC relatable. I've added a lot to the game since this demo, so I hope you'll enjoy both the next demo and the final release~ 

Awesome game so far. My only complaint is the glitches during the periodic table run-through. Often the text, the table and Mr. Kagaku overlapped or shared the same space, making it a bit hard to read. Besides that nitpick I LOVE Basil and the MC is also intriguing and fun to play. I look forward to learning more of her backstory. (Why is WP so important to her? What is she hoping to achieve in her life?)

Keep up the good work and I look forward to the Beta

Thank you!

Hmm, I've made a lot of changes since I uploaded this first demo. Hopefully that glitch has been fixed, but I'll check it out. Thanks for bringing it to my attention.

I'm glad you love Basil and the MC! When the beta comes out, some of those questions may be answered... but not fully, of course.

great game

Thank you very much! C:

your welcome

OH MY GOD. i loved it.  (✪‿✪)ノ

The art style, the character, the ambiance and the theme. Your art style is really good and amazing. My fav character is the teacher (♥ω♥*) (i always had a thing for teachers) but Basil is really interesting too, even if he is mean now i find him cool and cute. The only one im not really liking is Sidney (sorry i hate fuckboys :0) But he still alright :) . For the chemistry part, eh, i know nothing so yeah it was really difficult. I tried to understand what the teacher explained and followed the lesson but arrrf i like stayed 30 min trying to understand. And i got 2/5 on the test. I still like that you added that to the game, its original !You did a really good job and i'm really impressed on how you progressed since you started doing this game. woaw. Keep up the good work !


I was so sad when the demo ended. I want more ! I'm really looking forward to this ! :D

ps : sorry for bad english <:

Ahh~ Thank you so much! Don't worry about your English. I think it's great! I'm glad you like Mr. K. and Basil, but I'll do my best to make all their routes exciting! 

I'm happy you appreciate the chemistry part too! The reason I wanted to make this game was to try and make chemistry a little more interesting while I studied for exams, but of course, going through lessons will still be difficult... 

Thank you again for your encouragement! When I update the demo, it will be extended so you'll get to spend more time with the boys~ C: Hopefully that will be soon...

I really loved this demo! The game is really interesting and I was dissapointed it ended so soon. I am really bad at chemestry so I understand why the protagonist finds it also really boring xD. Anyway, I hope you continue with the story. It really is amazing and compelling :D

Thank you for playing! The next time I upload an updated demo it'll probably be more than twice as long. I hope you'll enjoy that one too! I'm also really glad you like the story. I'll do my best to keep it interesting!

Hello! Your DEMO has been in my game queue for a while, but I finally got the time to play all the way through! I really like it, and I'm going to write an entry about it all in my blog, but I wanted to give you some feedback before that. So I got the questions you posted in the forums:

1. What do you think about the story/premise? Would you want to play it?

I think we've all had a crush on a teacher at some point, so it's relatable on that front. Overall I like it.

2. Which character seems most interesting? Who's your favorite so far?

I love Basil. Sassy smart boys are kind of my thing. So he's my first pick, but I find Mr. K and Sidney interesting also. Mr. K's chemistry jokes are killing me, hahaha :D

3. What do you think of Marina? Can you relate to her? Would you want to play as her?

I was never the athletic type so I wouldn't say I relate to her on a personal level. I like her, though. She's cute, and seems genuine.

3. What would you like to see from this game? What expectations do you have?

Romance and drama! I mean, so far it seems good. More puns!

4. How do you feel about chemistry?

I've taken lots of Chemistry classes, so good enough, I suppose. Haha.

5. What do you think of the current character designs/art direction?

I love your bright and colorful art style! Basil's hair? Love it. <3

6. Any other thoughts, comments, or concerns?

I love the Chemistry Education sprinkled in. Overall I'm looking forward to seeing more!

Oh wow! Thanks so much for the feedback! I'm looking forward to reading what you write, and I'm glad you enjoyed it so far! C:

I really like the concept and I'm SUCH a chemistry nerd (though I am only doing exams myself, heh) . The GUI is cute, the colours are eye-catching and the chemistry puns were so, so bad (I'm a sucker for bad puns, even more so nerdy ones) - I love it. There are a couple things I'd like to mention though:

The in-game menu buttons don't exactly align with where they are, so I had to keep clicking lower, where the actual button was to return to the game after saving.

This is my inner nerd speaking, and a minor detail, but "Which liquid has the highest boiling point?" and giving the answers as HF, HCl, HBr, and HI might not be the best answers, since they're all gases at room temperature at the very least... unless you're talking about when they're dissolved in water. (save for HF, which is only liquid at just below average room temperature.) [Also, the hydrogen halides in general is pretty dodgy to talk about trends in boiling/melting points.]

I think for Marina's eyes, I think they look "creepy" for lack of a better term because we can see the bottom of her irises on her normal face? I'm not exactly sure though.

That's all I have for now. I'll keep an eye on this! :D

Thank you for the feedback! I'm glad you enjoyed the puns, haha! 

The in-game buttons being off is a first for me. I made this on a mac and play-tested it on both a mac and windows pc, but everything seemed fine for me. It might have something to do with defining hitboxes (which I have no clue how to do, but I'll look into it). 

You make a good point about that halogen question. I'll probably end up replacing it since I didn't like the question much myself. I'd like to replace all the questions with some that are simpler to answer. Thank you for your feedback on this topic! 

Hmm, I'll try doing some variations with some new eyes, and I'll ask the community about it later. 

I took another look, and I think that just may be a fault on my part - if the mouse wasn't hovered on the word itself, it didn't register, so if the mouse was like, a pixel from the word, it looked like it wasn't working. It's a little finicky, but it works, so that's on my end, sorry!

Oh! Thank you very much for clarifying! C:

Okay well I'm  not sure on what to say exactly but i'll try anyways!

First of all your art style definitely caught my attention. I like the different textures and saturated colors are my weakness. I died at that pinched joey wheeler face marina was pulling at Sidney. Like, how does anyone continue a conversation with her with that face being made? lol Though I feel like there's something off with her eyes and i tried to figure it out since I didn't feel that way about any of the other guys' eyes and I think its the size in comparison to her other features (mouth/nose). that may or may not be it.

The story is pretty interesting, though its nothing dramatic I think the way you've made the characters will be the standout thing other than the art, oh that and the cursed chemistry theme. Like I hate science with a passion so the story was that interesting for me to still try the demo anyways! I got like a 2/3-5 for the quiz so idk Marinas just going to have to fail in the full version with me playing.

I was looking through the game's topic on the forum and I didn't know this was set in Hawaii but it makes a lot of sense now. (floral shirts for all) As for the cg styles and such I say go for whatever you feel like or what feels right, even mix it up if you want. I know a few VNs that have different styles for sprites/cgs/ect i dont see the problem!

Like I said before the dynamic between the characters are interesting enough to make you wonder how the whole mutual tutoring thing will turn out and whats up with the underlying drama going.

Good luck with your finals!


Wow! Thank you very much for your feedback! I've gotten some comments about the eyes before. I'll see what I can do to make her less.. scary looking?

LOL, i'd imagine Sidney was sweating through that entire conversation while Marina was making that face.. 

You know what's funny? Every time I play-test this game, I never get a 5/5 on the quiz, even though I wrote the questions.. I'm no big fan of chemistry myself, and when I was in high school, I created these characters to help me get through chemistry class. Hopefully they can help players get through chem too. xDD
