I really like the game especially its art, music, controls and produrally generated maps! The game is very fun.
There were a few bugs though. I got stuck at 7th level because I spawned slightly below the floor so I couldn't move. Also at the end of some level fps dropped very low. I don't know why maybe because there were too many stuff on the screen.
Also some levels were too easy because the green portal spawned near the starting point. It would be cooler if it appeared at the other end.
