good prototype for game mechanics, but nothing much else really. Sound graphics etc, some motivation to play the game would be nice

Wow! Loved the smooth movement of the box! Good controls and good handling of the box. But You need at least sounds, and music would be good to add some atmosphere. Also You need some kind of introduction, I think. But until now, I like this experiment very much! Keep it definately up!:)

sure, it looks cool, but some sound and storyline would be cooler.

It was fine until I fell into the walls in level 4 I think

i don't understand the objective of the game. It has a somewhat good artstyle, but it doesn't have music, and wherever i go, i go back to the beginning of the game. You need to put instructions or a tutorial level and add music. Also, draw your own background instead of making it a pile of trash...like literally, it looks like debris and trash.
