The art here is charming, though I had an issue where the window didn't seem to fit the game properly. It looked like some of the top and bottom got cut off a bit.
Gameplay-wise, I like the climbing auto-platformer style, but I found the hitboxes hard to deal with. Sometimes I would bounce off things as expected, sometimes, I wouldn't catch them (assuming I didn't get high enough). I beat level 0, and tried for probably 5+ minutes to beat level 1, but never got to the end. I expected the cat hands to be a friendly thing, but the seem to kill me - so I'm still not sure what those are.
One thing that I think would greatly help the game feel is to have the camera get ahead of the cat when you get the buttered toast. I think I died almost every time I got a piece of toast because I would be able to react to enemies coming in from the top of the screen.
But those things aside, this is a great base for a game and could feel really good with a couple small quality-of-life tweaks.
