This is an impressive game. Controls, graphics and sound feel very good and polished. The pixel art is really nice. The mechanics are well implemented.
But it feels a bit like a tech demo. I think the random nature of this game does not work very well to be honest. I was missing a bit of direction and motivation other than exploring all the great stuff you guys have put into this piece. With a more distinct level design and a bit of exposition at the start, this will turn into a really nice game, if you decide to put more time into it. What you have submitted is in my eyes a very well functioning and fun to play fundament for that.
