@ RayCast()

This engine is currently lacking in more important pixel movement related support, unless its been added in 500+. Simple things like being able to calculate and move at angles, even a simple redesign to the controls, so you can use more than one movement button at a time by default, etc. This is all stuff I've already had to build into Box Zombies to get a simple top-down 2D shooter working.
EDIT: That's also a nearly 5 year old post being bumped, such speedy progress made around here =P

I've been banned from bug reports for a decade now, and don't use the 499+ versions of BYOND, but logging in to this for a quick test (SS13) http://www.byond.com/play/159014470. Walking around for a bit, the background/tiles clearly become corrupted in some way, drawing things that shouldn't be there. The audio (music) seems to have cut out after a few seconds, though I can steal hear random sound effects from messages. And after a short while, the entire map portion of the screen just blacked out on me, and doesn't seem to be coming back.

EDIT: Also, it seems the web client re-downloads the resource package every time you connect, not sure if that's truly a bug, or just a technical limitation, but not exactly a desirable feature either way.
