YES.
I love this! The level design was splendid; you introduced concepts slowly, and gave me the little pickups as gentle hints while still giving me a feeling of accomplishment. I can tell a TON of love and thought went into the 5th level especially, there were some real "aha" moments and going all the way around felt so satisfying.
The music fit well (idk if you made it, but if so, great job) and the whole aesthetic was really cohesive.
The limitation seems like such an obvious idea now that I've seen it, but I never would've thought of it!
The only thing I was missing was a back/undo button. I accidentally moved into a wall, one step away from finishing level 4 haha (I won't dock you for it, though, of course)
Brilliant, brilliant work, a fun play all the way through!!
