I love this kind of game! Maybe I'll get to work on such a concept later. But it was sufficiently entertaining. The shader/vignette effects were very nice! Quite unfortunate that there was no sound, even a simple music track would've elevated this game a lot! The only other complaint I have is that there's no "back" button when I click on the combine section. It forces me to combine the plants. Maybe another thing would be that I would've appreciated a second "level" but I think i'm asking for too much at this point. 

I can only say nicely done for a solo game! I hope my feedback was insightful!

Very good concept, nice work ^^

This idea is super original! I literally told myself: "OK, just 5 more minutes of this game, I have to find the cure."

Had a bit of a hard time with the dragging mechanic, but otherwise solid game :)

Very cool idea, well done!
