So anyone else playing this? Just finished Stage 1 and have been having a lot of fun with it. It's a no-nonsense combat RPG. You just go from mission to mission killing everything in your path with the occasional bit of dialogue interspersed throughout. There's almost no setup other than "You are Black Rock Shooter, humanity's last hope, now go kill some stuff". It's a nice change of pace from all the bullshit you'd normally need to deal with before you can get into an RPG.
Very simple battle system as well. You can shoot, guard, dodge, use skills (on cooldown) and items. The game starts out really easy, but the first stage boss (mission 5) definitely required you to learn their pattern. Well, assuming you wanna get through it without using items. Sadly, there's no retry option as I would've liked to replay the fight until I perfected it, but I'm too lazy to keep reloading my save. If you do die though, you can either choose to restart the mission but keep all your character progress and items, or reload your last save.
Overall a very pick up and play RPG that anyone can get into.
