I found it quite fun, and somewhat difficult. And all of those who want other attack spells, Check the wizard's name, Frostorn. I believe he is meant to be a "Frost-Aligned" Wizard.
The game itself is good but it lacks any real challenge. The game lags a lot even on the lowest settings. The game DESPERATELY needs a zoom in button. The upgrades are ok i guess but i really need more than 1 attack spell. It got sol old clicking the same ice bolt spell over and over. Ever heard of a fire ball or lightning bolt?
It definitely will be in sequel
The game's alright, though I feel that it relies more on spamming spells that any real strategy.
Fun game, played the whole way through. Perfect difficulty. Loved it!
As others have said, please allow people to zoom the screen. (affects linux just as much as windows or mac)
Really like the game. Somehow feels a bit short though. The upgrades are effective, but I don't feel fully engaged (stopped after 36 skulls). Magic drains too fast for a shooter. Pretty good overall though. Story was short and effective -- just right to give a setting.
