I love this kind of bouncy puzzles, I had fun trying to figure them out!
One remark though, the difficulty curve was quite steep between the first and second room. I think it would be good as it is later in the game, but maybe lacked a visual cue/logic to point to the solution.
EDIT: Playing it a second time, I was also surprised I could just walk into the rooms and on the guards; it allows finding solutions by standing on one of them, and checking every direction until it aligns correctly. :P
