This game fuses a top-down shooter and a dating sim. Essentially, you play as a voice within the head of a typical VN main character.
To sum it up in terms of more well-known things: Doki Doki Literature Club + Hotline Miami + Inside Out (or Everyone Is John)

Unfortunately, as a voice within Kei (the main character)'s head, you're not alone, and even worse the other voices are willing to use force to take control of our poor MC.
But maybe, if you can keep control, you can help the main character find love...
...or you can just let the others take control and see what hilarious and/or horrifying antics they get up to while in control.
