Simple but very effective concept! I think some indication about where the available movement spaces are, if that makes sense, like a different image to portray where the wizard can move to, because I was having a very hard time figuring that out and even though your instructions are very clear, I at first assumed I would be able to move around inside the grid, not on the bottom part. Otherwise, had lots of fun with it, I'd love to see more types of attacks, maybe some that have higher costs but longer range would be nice.
