I really liked the art, I thought there was still some stuff to do after returning the rock kids, maybe you should put a message telling when the demo ends.
Thanks, I'm currently honing the platforming mechanics. I'm leaving it this way for this jam, but in another I'll use better distributions between the tiles and the player's movement.
Thanks for you feedback, I'm currently learning the use of Asprite, so I can make my own assets. I'm also looking for a way to make some sfx's and music.
The art and music are pretty good and the gameplay is ok. The only problem I had was that the gems sometimes stopped my air time, also the wall jump is a bit complicated to use.
