Really elegant concept. Like how much you get out of so few rules.
Really nice to see more puzzle games with undo support.
The first level was slightly confusing, I didn’t really understand the movement until I was into the second level.
The 8th level was really great, had a big a-ha moment there!
The 9th level felt slightly too easy compared to some of the earlier ones.
Maybe it’d be nice with a few easier levels early on?
But again, really cool mechanic, and well done to create so many mostly well-balanced levels in just one day.
