Nice paced game. My first thought when I saw the "-1" while hitting the enemies was "Great. There is a way to improve the basic attack or maybe a charged attack" But couldn't find any. I guess that having the "-1" is rather pointless then.
The arrow system to cast magic spells is MARVELOUS, really intuitive and adds both another level of balance and difficult to the spells. The art and music are on par too! they work really well.
Congratulations! Great game!
