Played it and got stuck on the 5th level. There are some genuine ideas for a platformer, but are often presented in an unbaked form. Look up several game design videos for platformers to get the gist of it. Graphics are wild (surreal some might say) and I didnt read up the lore, sorry :(. Keep up the good work!

By 5th level, you mean the one where the 2 characters are seperate and there's a conveyor belt?
If you fell off the belt, there's still an area with a teleporter where you can return to the belt, but you can still control the companion to activate a blue platform that leads to an area with 2 keys.
The game is pretty much my first, where I used it to learn stuff and also an excuse to show off characters and settings I thought of for a while.
