I really liked it ! For some reason, my xbox series controller didn't make the cat jump (only moving), so I had to play it on keyboard.
I managed to finish it, and I really like how difficulty increases. It may be because of the keyboard gameplay I had to go for, but I find it almost easier to only keep the cat jumping never releasing spacebar, because it's possible to bounce on dogs.
The only part that surprised me was the two platforms on top of each other : it's really strange that the cat seems to teleport on the one above. I really like how the cat respawns on death. We created almost the same game (collect things avoiding ennemies until a final flag) and I find your solution way smarter and less punishing than mine. Great game ! :)
