The same person, yes.
Climbey and this game are both made by me, alone.
Yeah it is, it's on the workshop called "demolevel" lemme find a link...
Just subscribe to that and you'll be able to put it in the level playlist through the level selection menu in the left front corner of the main menu. :)
There's more to craft!
But I currently don't have plans to update it more, it was a quick little jam game and I have a game about to launch on steam I'm working on, sorry.
I may do a quick update to remove the distortion though.
