Diorama Battle of NINJA is an action game (Shooter, I guess) by X-Stream-Digital, released in 2016. There are lots and lots and lots of enemies, and you can run (really really fast, if you want) over everything.

I'm not quite sure how the title works, it also has 虚拟3D世界 忍者之战 on Steam. Not sure if that's a subtitle, or—

The controls are pretty simple. Stick or WASD move your guy, the four face buttons are the different weapons, B being the unlimited shurikens you'll be using constantly, and the left shoulder button and trigger make you run really fast.

As mentioned, the B shurrikens are you main weapon. The A button weapon is like a landmind. handy to drop if enemies are chasing you. The Y button attack is really great against tightly packed groups of enemies, and homes i non enemies. The X button attack seems to be rare to collect, but it a really strong wide flame attack.
