Good for a first work, lots of room to improve
Considering that this is your first submission, you have done a good job and I'd encourage you to continue and get better
Some things that you could improve with
* generally decent graphics, but there is a lot of flickering at the start
*music plays over itself when you "replay"
*maybe an indicator of how much hp a spell uses?
*your special can be done with negative hp and it will continue to be negative.
maybe another font?
Anyway, good job and I look forward to seeing more of your work as you mature
