The game is quite fun for a short game, the camera move is smooth. But you can make it better by getting rid of friction, and for a platforming game, i suggest u should try to implement things like "jump buffering", "coyote time" for better jumping and correct player's mistake. I would also suggest another things for smoother jump like holding jump button to jump higher, i see a lot of potential in your game!

Fun short game would be made 10x better with just few sound effects but still pretty nice.
