Nice game! The music, gameplay, and art are all good, and I especially liked the bomb explosion effects. The level design was kept tight, so I didn't miss having a map or checkpoints too badly. I don't know if this was intended, but I actually managed to beat the game before getting the final bomb type. Seems like I hit a switch with a regular bomb that should have required the last bomb type. I was having fun though, so I looked around and found it after ;)
