Akane feels very much like an arcade game. The entire game is one screen with an unending supply of bad guys that you have to kill. Every enemy dies in one hit, but so do you.
The gameplay is really fun though. You have a sword attack and a gun with limited ammo that slowly refills. You can unlock more swords and guns by accomplishing various tasks (block 10 bullets, reach a combo of 50 attacks, etc.).
The game is available on Steam and Nintendo Switch.
Also, I don’t know if there’s a name for this style of game but I recently came across Kill The Crows, which has the exact same game mechanics (and artstyle?) but with a Wild West theme. It’s weird how similar these two games are.
The game does look cool. I doubt the longevity of it, but I don’t really think this is that type of game though. I think I’d have fun with it, but I’d also get bored with it pretty quickly.
I just can’t get over the fact the character has a cig hanging out their mouth the whole time XD
