I had a good time with this one -- it's just the right balance of action / fighting to puzzle, in my opinion!
One thing I did find a little frustrating though was that TP didn't carry over between battles. I intentionally didn't use one of Luna's skills because I was building up TP for a stronger fight / in case I needed it.... And then the next battle she was back down to 7. That might be something you want to look into changing, if you're planning on updating this at all.
Thanks for sharing your game with us! It was lovely. :)
