Nice game, I liked the simple moving animation.

Looks like my comment didn't post... Good start. You could build a good puzzle game off of what you have here. 

Fairly solid idea for a puzzle game. I liked having multiple ways to split and move everything at once. The hitboxes need some work and I think the game logic only seemed to need the blue object to unlock the gate and I think you move too slow, but you seem to move faster on the levels where you have four colors. Really a good foundation for something that could be a lot of fun though. Good work.

I'ts a good start. I first though that the red and blue guy was a single animation then I realized that you could slightly move them away if you push against the walls. Just didn't understand waht you were suposed to do in the level where there are just walls around the blue square.

Could you check my game by the way?
