The game is a 2D beat em up from the 00s or early 10s (not likely). The character was a blonde woman with a sword in a natural lanscape. The genre was fantasy. She had a sword and gold coins would fall from the sky after completing a level I think. The game was a Japanese import or something so adoubt many people seen this game.

The game looks a bit like the hentai game Final Fuck but with better graphics. I kind of remember the game being a dedicated machine but not sure.
