Thanks. I also think that the concept is interesting. I hadn't barely use Unity's 2D rigidbody and that cause me the troubles with collisions that you mentioned. I will take more care about controls and the rigidbodies in the next jam.

That was the intention. At the beginning I was thinking the way to move the platforms. One solution was like Oeufwakening, with  the mouse, but I chose this solution becuase it minimize the controls. It will be funny if I had chosen that way and the two games had the same mecanic XD. 

I didn't have enough time to fix the physics, collisions, controls,... because that weekend I was doing other things. I didn't have time even to change the character (is the default 2D character of Unity >.<). I was doubting about uploading the game with all of the things that I want to change, but you two (edmond00 included) showed me that it was the right decision . So thank you two ^^.
