Very fun puzzle platformer with really charming pixel art! The visuals are very polished and the music is great! I also really like the complexity of the later stages (except stage 8 though, took me way too long to figure out you could just beeline straight to the flag lmao).
I did find a little bug which clips you into the wall. I know it has been said before, though I think the situation here is a bit different, so I thought I'd point it out just to be sure :>
This didn't affect the gameplay at all though, I really enjoyed it! Really cool game :D
If you stand under a block like this:

And get on the block you'll get clipped into the wall like this:

Same for another level:

(just ignore all the screenshot ui stuff):

Also you can get something like this:

If I'm right you can just fix this with a raycast pointing upwards from the player, hope this helps!
