I have to say it's pretty impressive for being made in one day. Although there are a few issues. The controls are a little odd, I assume you use a french keyboard hence Z being forward. For future projects you'll want to assign physical keys when making actions in the input map, this should make it so the controls are based on the position on the keyboard rather than the character pressed. The explosion sound effect is funny the first time but quickly becomes annoying due to how loud it is. But other than that this is a cool platformer, the control reverser is a interesting mechanic and the movement is competent.
