I think the character is very cute, I wish the camera would scroll itself instead of having to manually use the scrollbar though, it’s really hard to play like this

I like the concept of the game. I'm not sure if it was mean to be on purpose but you can get through some of  borders and the objects which defeats the point if it is meant to an obstacle.

Nice work. The graphics look good, and the progression of levels so far works. I would make the game window in itch.io match the size of the viewport so that the game is full visible, or set the game to open in full screen. There are some issues with the platforms as we've discussed, but it's not so bad that you can't finish the game. The jump goes very high, which makes sense for the space theme, I think it might be interesting to play with the placement of platforms so that you can jump up or down and discover new platforms, maybe make the gravity lower too. I would space out the UI a bit too so you can more clearly see the sprites and numbers being displayed.
