The art style is really charming, the colour palette is lovely, and decorating the page to match really pulls it all together.
A few notes on balance: checkpoints and a bit more jump leniency would go a long way. Some of the difficulty seems like it might not be fully intended yet, the ocelot(?) near the start felt almost impossible to dodge, so I ended up just eating the hit each time. I also noticed my jumps not getting triggered a few times, which made platforming feel less consistent than it should.
One possible bug: at one point I died right at the edge of a platform, and it looked like the water collision might have triggered early.
Really charming entry overall, and I think with a bit of polish this could be a genuinely fun, cute platformer. I wasn't able to finish it, but I'd love to see where you take it.
