That was fun to play! I like the cat, the camera shake, and the idea. If you're ever going to work on this again, here's a few suggestions I can think of.
Suggestions:
- The catto feels heavy, like gravity is working overtime to bring it down - unsure if this will make it better, but a bit of longer airtime maybe could make it feel better?
- Resized pixel art looks out of place, keeping every pixel the exact same size and just drawing them bigger would significantly look better even with simple art.
- Cat disappears into the door when jumping up right underneath it
It's a great game specially for your first!
