Very cute! I loved the music, and the overall vibe was nice - so many platformers are hardcore and precision-based, it was nice to play one that's forgiving and soothing. It would be interesting to have some extra inertia on the cat's movement, and I also had a few camera issues in the browser version (in level 4, I got all the way to the top but couldn't see below, and fell to my death...)
I look forward to seeing more!
