v0.4

Add a log layer for adding text infos on qwerty/azerty mode or print technical info.

Dirty fix a "levitation issue" in certains case pressing space did that the jump will never totally end making the player levitate one case above ground.

Add a jump capacity variable.

I'll updated the itch page a bit, adding a logo, a better cover image, styling the page a bit.

Rename Sprite object to Graphic (because sprites are not "pterodactyl graphics").
