BSR has two versions, C67 and C74, and they're pretty much completely different games-different boss attacks, stages, scoring systems, everything. C67, the earlier one, is pretty good, though the bullet patterns are different and sort of an acquired taste (and it's depressingly hard T_T). It's the one with the timeout final boss (and oh god she's bullshit).
C74, however, is horribly planned out, with the attacks divided equally between memorization-gimmick crap like the example above, or undodgeable attacks that are pretty much made to be bombed through. It's not fun at all, and I wouldn't recommend it to anyone really.
