I think the idea you had in mind is pretty good. Especially the addition of enemies is a plus. I was standing next to one and two walls were between us. Next second the walls were gone ;) This could develop into some really interesting gameplay. Too bad you didn't finish it. Hope to see a game from you next time!

Too bad you coudnt finish it.

I like how the maze changes from time to time. Thankfully, when I get impatient, I can just tear down the walls with the space bar; but that would make the game too easy. A limit of how many times you could break the wall would be idea.
Good thing you have enemies in this game, but they need to be a bit tougher. Maybe allow them to break through walls as well when they go against a wall for a few seconds?
Good game overall!

This is an interesting idea, I could suggest many improvements but I won't since it's clearly unfinished :) Better luck next time!
