So yeah, I've gotten this recently on both PC/Steam and Switch, and can say that Bikkuri Soft doesn't miss and brings out another banger STG. All I can say is that its good. Just like both versions of Graze Counter. Also...

Entering the name of the specific character in the Name Entry in Configuration also alternatively unlocks them in the Omake! (Neko-No-Kami) mode without having to spend credits in the Unlock Shop. And technically, its skins 1-8 that cost 1280000 each, skin 9 is 2560000 and skin 10 is 9999990. (You can also type these in the Demo version, but they don't do nothing since the Unlock Shop is disabled in the demo.)
The list of names (in order from the shop):
Most of the names are from characters previously in Graze Counter GM (outside of Kamikaze, which threw me off, cause it looked like the character "Lily". Had to look hard for that one until now). You can also input additional names, for example, like "Shizuku", "Akane", "Necobi", and "XYRS" for extra character specific avatars or something, but chances are, there's probably more than just those 4 (some of those names you can find in the credits). If any other names pop up, I'll probably update the post, but no guarantees. Either way, the game is currently at updated versions .0301 on the PC/Steam and 1.03 on Switch (as of post).
