Not, it does not suck at all.
Nice idea, not bad to play, but not a complete game, that's true.

often in non-completable levels. getting stuck on walls isn't fun.
It seems it's possible to glitch death by holding down escape

It's way too easy to die!

it seems your levels randomly generate and thus can make the level unplayable. but very interesting start to what could be a very fun game.

Yeah, random generation may not have been the best idea, and the game needs more work (permadeath? :( ) but it's a good start!
