Awesome idea and polishing, the game looks very professional.
My biggest issue was the controls are very unintuitive making the game a lot harder to play than necessary. I love how animation you made it look and the presentation is top notch.
Thanks a lot!
I agree with you, the game quickly turns into a space/arrows mashing marathon. I originally intended the molecules to be drawn with the mouse, but since I never tracked a cursor before, I had to stick with the keyboard, unfortunately (and the massive wall of text I wrote to explain it doesn't help at all :/ ).
In the full version of the game, it will however be the case!
