So what about a 64 x 64 FPS, and threw together some assets models in Unity and managed to make this mockup:

The image shows the number of enemy robots left a health bar and ammo, a green crosshair over the distant (few meters away) red robot.

Will add a scope so player can go ADS on distant enemies.

The idea is a free flowing FPS game but in a maze with 4096 enemie robots to destroy.

Closer look at enemy robot and changed the players gun colour as it looked like part of the robot.

Should I try and make this?

It looks cool, I remember seeing an asset for Godo, although it was broken, the idea seemed interesting to me even before the jam.
