For only having 2 days to work on it, this is nice. The basics are all there.
The levels appear randomly (procedurally?) generated. Occasionally, I got a room that I could actually get to because the platform was too far. I'd like to see that corrected in round 2 (if you chose to continue this game, of course).
Art was pretty good. I could definitely get the slime and tower parts straight away.
All around good entry!
