Identify Game similar to plants vs zombies

[Monochrome]

Hello everyone!

There's a game where you play as a high school girl and have to cycle between different types of guns to shoot down an onslaught of approaching students/workers in school. I can't seem to remember the game's name.

It's not -exactly-like plants vs zombies but the idea of switching between weapons vs different types of enemies is the closest thing I can remember.

And you could chose different levels, and unlock weapons? If so, I played it as well, and im nearly certain there is a "Love" in the name of the game, or developer, but I cant seem to find it (yet).

Edit: Alright there kinda is the Word love in the title, since its this game I was talking about https://f95zone.to/threads/amour-octopussy.21981/
