Check out the screenshots for my Tunnel game! Made with Axe 1.2.2. The tunnel gets smaller by one pixel every few seconds until it is about twenty pixels wide. Game is completely random every time you play.

Damn ClrDraw! It was like just yesterday when you signed up! Nice job on getting stuff out so quick and nice game! +1

Lol, thanks!!!   I'm adding a few projects I finished a few months before I joined!

They are, and it was surprisingly easier to program than many other things I've made!

Scrolling up/down might actually be about 60% faster than left/right, too. (about 16000 clock cycles versus about 26000).

No he is talking about scrolling the screen vertically vs horizontally

It is indeed Here, check this out and click the little button thing at the bottom to show speed/size for various outputs.

It turns out my estimates were off, though, and it is actually even faster than I predicted

Internally, the calculator stores the screen buffer as a 768 byte array. Each byte corresponds to 8 pixels (8 bits per byte) and the screen is horizontally aligned, meaning the first 12 bytes (96 pixels) correspond to the top row and it works down the screen from there.

To scroll the screen down or up, we only need to shift 12 bytes which is pretty easy to do-- there is an instruction that lets us copy a number of bytes from one location to another, removing a lot of overhead code.

To scroll the screen left or right, we need to shift by 1 pixel and there is no easy instruction to do that. In fact rotating or shifting bits requires an extension of the instruction set, which makes it even slower to rotate by bits. (shifting by 8 pixels left or right is much easier as that becomes once again, shifting the buffer by a byte, which is easy)
