Hi Alex, I played your game, I read a little about it. As you said, it's a simple game. To be honest, my only complaints are about the levels and the jumping.
It's something really silly, but I think I'd better say it
1- Levels: If you click to go to the next level, and accidentally press a letter on your keyboard, the game screen turns blue and you have to restore the page. It's just not that boring because it has the checkpoint.
2- The Fall: When you are going to jump over the obstacles, the cat falls very quickly to the ground, as if it were a magnet pulling it
In all 20 levels, these are my only complaints.
In fact, I saw a drawing you made about your cat, man, you draw very well, the background of the game is also very beautiful, I'm not going to lie, I enjoyed it while playing, seeing the stars falling was cool :) .
