Wow, super unexpected but this was a ridicilously fun game! From what i thought was gonna be a walk around rpg, turned out to be an insanely hard puzzle game! it really made me and my friend think, but it was so fun!
I would definetly reccomend trying to make easier initial levels, introducing the concepts of the game to the player, and then reach these harder ones, but other than that, the game and level design was great
