I looked at the spells. They're done way differently. It's interesting but not D&D. For example, I think Fireball is like 6th level and does 3d6+small bonus damage. Three levels have been added to a lot of spells. They've been made more interesting in some ways; the Shield spell (still 1st level) casts itself whenever you get hit, making it a sort of one shot force field that gives +4 AC for one attack. All classes get spell like abilities and they go up to level 29.
It's way different.
