Good:
- Aesthetically, it's absolutely lovely. The sprites are charming, the environment all feels cohesive, and the use of musical notes for sound effects is really interesting.
- I liked the level design. It looped back on itself very nicely, and I felt like there were lots of directions I could explore. I also liked how the camera zoomed in on the vent sections. That made them feel darker and spookier. Since it also made it easier to run into enemies, I had to be more cautious, which felt appropriate.
- I'm impressed with how clean and simple the control scheme is. You managed to get three fun abilities into the game, with only five buttons. In fact, I never needed to drop through a platform, so it was more like four buttons.
Bad:
- I liked the sound design overall, but I feel like it was a missed opportunity not to include cute cat noises. More seriously, the landing sound feels a bit odd for such a soft-footed animal, especially when landing on cushions or sofas.
- There were a few dead ends with just enemies in. At first I thought I was supposed to purify all the toy mice, but some of them seem to come back, while others stay purified.
- I'm splitting hairs here, because there were so few problems with the game, but the ending animation made the girl seem like a 2D cutout. Nothing had used that aesthetic before, so it was a bit jarring.
Overall, this was a beautiful, thoroughly enjoyable game. I really enjoyed it, although I am biased towards anything cat-centric. I think you scoped really well for the jam, and hope you consider a more expanded version in the future!
