Three reasons to be going after the treasure:

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.

...well... This is awkward.

Yes, I CAN make an animated background within a matte, with a shifting color palette. However, I realize this doesn't look like lava, no matter which way you shake it.

...the effect's cool, though.

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

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...

Robots fresh off the assembly line from the prosthetics factory.

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

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.

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.

I made an up-to-date trailer for Terry's Treasure Trouble!

You know, in case it wasn't clear what kind of game this is.

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