Interesting concept and I like the little character sprites! It'd be good to have some kind of explanation in-game, it's quite confusing to just be thrown in with no directions. I'd also like an on-screen score, as you can't tell how well you're doing until you're dead.

i liked the idea of moving the walls to destroy enemies! 

Hmm, there are good ideas here, but they're somewhat haphazard.

The fact that the game progresses while you're on the title screen is a bit confusing, especially when you die before starting the game.

The biggest problem is the random, unforeseeable monster spawns. If monster spawns were telegraphed, it'd be more compelling to move the character. As it is, the least effort strategy is to move to a corner, squish the walls all the way in, and then gamble on an enemy not spawning on top of you.

The art is cute!

Congratulations on the submission!

What is this game supposed to be ? Pretty much the only thing you do is staying to the center and closing the walls on the enemies around the edges until you randomly die (there's no spawn indication). Also some of the buttons aren't even used and you don't even know what you inputed because there is barely any visual cue.
