Are there more keys besides WASD?

Like the idea, needs a bit more of a tutorial and a tad tighter controls.

Develop this a bit more, and it could be brilliant!

rpmoura You run if you hold down space. Also I plan to Work on it some more and release a post jam version with more levels a tutorial and even a story.

Nice game mate, cool puzzles but should work on controls a bit more. Other than that it is fun :)

The physics did interesting things at times. Overall pretty fun, good job!

I kept falling through the wall of the 2nd room!

It was difficult, but not too difficult. I liked it quite a bit :)

The physics mechanics were really cool! I liked that a lot. I especially liked that if you pushed blocks at different speeds, they would react differently.

I would have liked some more separation of controls (probably space for jump and then up for climbing). Left and right were a little loose as well.

Frustrating mechanics as things keep sliding.
The level starts too abruptly and you are hosed if you ended up jumping vertically at the start of any level. If you barely had enough time to run across the room and climb the wall in one of the levels, how does adding boxes to slide onto switches that get in your way make it any better?

Not bad, but it got very frustrating, very quickly.

Wow! Great game! I stack on 4-th level. But wanna to try again later. thank you for interesting gameplay and impressive graphics )

Thanks for all the great comments everyone. I'm glad some of you enjoyed my first LD entry.
