Really cool game, no pun intended. Instead of being a permanent addition to the moveset, you made the special attacks and other skills into consumables, which made the simple combat more challenging. The art is great, tho of course there's room for improvement.
A suggestion I'd like to give is to move the "Frostbite" skills to right click. The attack button is already left click, so it would be more convenient in my opinion. All in all, neat game that could be expanded on.
