There is 50 level's in Crystal Story. The first 25 levels are to do with the main story quests and side quest's, while the last 25 are optional. Reaching Level 50 will give you an optional Boss. Vote this so everyone can see please. ;]

I like how you can choose what class each character is. (Even though it is most obvious what class they are by there looks and weapons anyway xD) The battle music is awesome!!
