I'll give this game a try.

I've been playing for about 2 weeks now. Probably the most addicting game ever. The bosse are awesome, especially the phoenix and collecting keys. it's hard though because you have to have to do a lot of exploring to find everything. you can even walk on top of walls like in Super Mario Brother like when you'd go to 1-2 to find the warp zone. that's how you get the spell stones!!
