I'm currently working (really slowly but still) on version 2.0 of the game (with a 100% already working level editor), but my plan regarding skins was to let anyone draw them and then I'll add them to the game, because I'm bad at drawing.
So globally when version 2.0 will come out, you'll be able to draw skins and try skins other people drew. I'll probably make a discord server for the game and for sharing skins and level.
Thanks for playing, stay tuned (>O^o)>
