Could use a little more tutorial or a more gradual learning curve. I almost quit on the first puzzle, but I'm glad I stuck with it! Very rewarding once I figured it out
I'm glad you stuck with it and enjoyed the game! I realized fairly late that the game was difficult because it was confusing to work out what you should do rather than because the puzzles were hard, which I didn't want. Unfortunately it looks like I wasn't able to solve that completely.
I think the blue squares for remaining ghost powers weren't super clear in the UI, it took me a couple levels to realize what those were. And maybe make an easy puzzle just to teach each new mechanic as you add them, then follow up with the challenging puzzles that use that new mechanic.
