This was REALLY fun to figure out! All the puzzles made me feel so smart, especially the final one. But uh, I was playing on the windows build and there were 2 .exes. I think the one I played on didn't have the ending coded in yet (there was a blue box but it had no collision?) so it's kinda disappointing I don't get to know how it ends unless I replay the entire game.
