This complete demo is a little better than the original. The collision detection still needs to be fine tuned. Graphics could be sharper and more detailed. You are getting better as you go.

lolo

It's a slight improvement over the last version. I did notice that you can push blocks trough walls. That's probably not intended.

This was a pretty decent demo, some things i would probably fix would be the collision detection for the ball/walls (im guessing this was made in gamemaker, in which case it's probably to do with the masking of the objects, using a uniform square mask would probably help) same with the boxes, i would restrict them from moving toward the direction of the wall they are touching to prevent them from ghosting through the walls. Over all though, most of the mechanics were functional and i was able to get to the end screen without too much trouble. With some polishing and updating the visuals a bit this could be a good game.
