This is a really nice and simple platformer! Well done on your first public release!
I made it through the first area before foolishly clicking "Quit Game" in the pull-up menu while looking for an option to return to the hub, causing the game to lock up. I'm assuming this was intended to be a downloadable game at some point?
The default control scheme is a little unintuitive, so the ability to configure custom controls in the menu is highly appreciated. I also think arrow key movement controls suit this game better due to the large amount of other keys that need to be used during gameplay.
I did notice a few bugs while I was playing. The final chain in 1-4 will cause the screen to scroll upward and get you stuck in the ceiling if you climb it all the way. The eyeball enemies would also sometimes be moonwalking when I entered the screens containing them from different directions.
