It's pretty good! Bosses have interesting patterns and are modeled after their most recent movesets - Blanka uses all three types of Beast Rolls, electricity, and an electric roll, for example. Each boss also has a super meter and super combo that can really **** you up if you aren't careful. Using Blanka as an example again, he electrifies the entire floor (like his Ultra 2 in SF4 AE), then throws four watermelons, then Beast Rolls through the watermelons. That's the kind of game this is.
