Really enjoyed the game, short and sweet! The puzzles were well designed, and I could easily imagine this being expanded into a full game.
The only thing I didn’t really get was the reason for the switching limit. I instinctively kept switching back and forth to see what is on the other side, only to lose due to too many switches, causing a reset. Seeing as figuring out the space is so integral to the puzzles, I’d personally get rid of the limit, or at least add an option to peek at the other side without switching. But ultimately, that didn’t detract from the experience much. Good job!
