Hell yeah I beat the second level!
I'd have to say this is your best game so far! Really awesome idea and well put together! I like that the cubes turn towards you once you spawn in. It gives them some personality!
The second level is a bit of a jump in difficulty, so I would probably dial that back and have level 2 for somewhere later in the game. Another thing I would change is the speed of the enemies. I feel like they should be slightly slower than you, that way if you do get past them you don't have to worry about then catching up with you!
Please keep making games! I want to see more!!!
