Interesting direction you took it. I’d forgotten about these kinds of simple puzzles, so it was nice to play some again.
The map integration is interesting. It could probably use more instruction windows for how to use the map view and for each puzzle.
The game lags quite a bit on the difficult puzzles that have a lot of tiles.
The drag panning could probably use a deadzone square in the middle of the screen so that it’s not always moving the camera.
It would be nice to be able to move the camera with WASD and arrow keys.
