You play Kurt as you played Kurt before, boss fights are lovely and some rooms are splendid.
Max and Hawkins were supposed to add diversity but their levels respectively get monotonous and annoying : you fight the same way you fight with Kurt (so so) ; the game fails hard when it tries to be a platformer ; the Dr's puzzles are far from clever or even funny.
Also, I like the personality and humor of MDK better but I won't blame Bioware for not being Shiny.
And about the soundtrack : i can't help but praise the lard.
