First off, you can't rotate a background with draw_background_tiled. However, you can draw anything on a BIG surface, and a surface can be rotated and doubled up.

So, the infinite floor uses a surface, and now it's not chugging so hard. Look at the FPS.

I might have gone too far in a few places, and not enough in others.

The only thing harder than animating a set of wheels is making it handle like a set of wheels.

...and making an infinite floor without resorting to the official 3D engine.

There are a lot of robot arms in a prosthetics factory. They flail about, so don't get too close, or they'll hurt you.

This background full of conveyor belts might make it a bit more factory-like, but it's still ominous.

Robots fresh off the assembly line from the prosthetics factory.

I call the ones that crawl "Gwendy", after the dolls from Small Soldiers.

Three reasons to be going after the treasure:

If you've had your fill of games where you play as elephants and blue hedgehogs, this might be for you.

...and I haven't advertised this the best, but it's coming.

Trying to do that Infinite Floor thing (technically, it's a trick of the camera), and I think it chugs.

Makes sense, since it's drawing on one surface over and over for each scanline, then putting that on another surface, which puts that on-screen.

Hmm...

What kind of bad guys do you see at a prosthetics factory?

These Leg Gunners are part of the security system.

I could have a part where the factory builds robots for you to beat up, but they're gonna be humanoids. They'd probably be like skinless T-800s.
