I really love this game. The art is gorgeous and I didn't expect to find some zombies chasing me XD
Most of the puzzles were easy to understand and didn't take much time to figure them out either.
I don't think I have something that greatly bothered me, though of course it could use some polish.
In conlusion, if you ever made this into a full game, I'd definitely play it. (And maybe translate it to other languages as well, I'm sure my mom would totally want to play this XD)
