Validating takes a while on boot code 1.03 (which I'm guessing you have), iirc it can get upwards of 10 minutes

I love to program on calculators and have fun with them.

Seems like you'll fit in quite well

The best way to learn Axe tends to be reading through the documentation. And keep a printout of the commands list handy
If you have any questions, feel free to ask around.

Mathprint was kind of poorly done, to say the least   The program editor bugs when used with zStart if mathprint's enabled. I'd just stick with classic (or better, 2.43).

On a different note that looks like one of the more epic ways to crash it, lol

I guess some of those could serve some sort of purpose..tho keeping in mind that it seems like we have more emoticons than we use
 

There's a computer Axe?

Yeah, tho looking at it it hasn't been updated for about six months..guess that might not work then

Sounds pretty cool. Never played any steam games myself but it's nice to see more options than the normal three companies.

I'm not really sure on what sprite size I'd go for, tho I'm leaning towards 8*8 for memory and simplicity.
12*12 would be great if it can be made to work optimally both space-wise and speed-wise tho. Maybe the extra 4px on the bottom sould be used for a hud or something. (softkeys?)

As for the grayscale, a random thought that came to mind was maybe it have monochrome primarily, and have an option to make it 3-lvl gray for shininess if the player wants it? If they don't want it they could just not send an appvar or whatever with the masking sprites.
