This is a very beautiful game with very interesting mechanics and art style. I love it. Although there's not much criticism that I have for this game, here's a summary of what I like and dislike about it.
What I like:
1. The new mechanic where you use your old dead bodies as platforms to both stand on and block traps is a very interesting and new concept. It also fits well in a 2D platformer like this
2. The gameplay is quite accessible and the controls are very simple
3. The art style is well polished and the color palette works well with the pixel art setting
4. The level progression felt natural and fair. I didn't feel like some of the earlier levels are harder than their later counterparts. The level design overall is well-made, which makes the game challenging, but still fair
5. I like the music
6. I like the bit of humor in the game, cuz why not have cats in a cat-a-combs :P
What I don't like:
1. The laser beam trap sfx seems missing, I'm not sure if that was by choice or something else, but overall, this is a minor issue
2. The soundtrack, while is very nice, adding more music pieces to it would've been even better imo. Like maybe one for the main menu and one for the levels.
Other than that, I can't find much negative things to say about the game, so well done. You made a very lovely game
