During the jump, the kitten has a small strip behind the tail. It doesn't look very good. It also shakes a lot during landing. I think it's best to remove the ability to control the character before it appears.
Sometimes terrible things happened on the screen. The kitten fell down, then took off and was twisted from side to side. Sometimes the movement buttons were not pressed, and sometimes the kitten took several steps at once. Sometimes the plates under the kitten disappeared, but it remained hanging in the air.
Alas, I only had the patience up to level 17.
In general, I really liked the project! This is really very cool! Especially the graphics! The graphics are just gorgeous! I can't even believe that all this can be done from an 8x8 texture! It's great! Your project is definitely one of the best on this jam! It was especially interesting to watch the process of creating your project! It would be great if everyone involved showed the development progress!
