There is a lot to like about it (art was cohesive and cute, sound was good), but there were a couple little things that annoyed me a bit. I wish the squares would stay up a little longer so I could see them when I was trying to move. Also as others said, spamming attacks seemed like the way to go.
Honestly, this shows a ton of promise. Even for a week long jam, I know how difficult it is to get all the rules and logic into a turned based game, so I applaud even just trying.
