I utterly adore that game. I put in over 100 hours too (multiplied by an unspecified prime number). I really like Magicka too, and was pretty good at it. Proficiency at that game is definitely a perishable skill though. I fired it up a while back and couldn't remember how to cast any of the good spells nearly as quick as I used to.
