Im sorry but I didn't get what I was supposed to do. I just flow down a little bit then up and left but even if I collided with anything nothing happend. I'm open to an explanation.

Well I downloaded your game but I'm not sure what to do, I went down for a long time and nothing happened ? Not sure if it is the right direction, but nothing tells the played what he has to do (or at least, give him a direction), and since there are no environment, it is impossible to know if I'm still moving or not. Try making games that go straight to the point, help your player understand what is going on, and never let him completely lost (not directly on start, at least).
But, remind that you built a game for the jam, and you can be proud of that. Keep up the work

HTML5 version possible?

Welp, I'm completely lost, I don't even know if I'm moving or I'm blocked by an invisible barrier. Doing a game without someone giving you feedback is really hard, don't get discouraged!

At first I was a little lost, but after reading the description I was able to play better
