Rocks'n'Diamonds

After you die or exit the level, robots seem to head for the upper left corner; as if they're reading the player's coordinates as (0,0).

I don't think this would affect any game mechanics, but would make after-game potentially more amusing: instead of heading for 0,0, could robots do a drunkard's walk or some other algorithm? (For instance: each individual robot could be assigned an 'afterlife' behavior identical to some other character's, like spaceship, bug, yam, etc.) (An easy improvement: instead of reading 0,0, read random(maxx),random(xy) so they're constantly stumbling around chasing a phantom player...)

Sounds funny!

Yes, this would be possible without disturbing any important game mechanics.

However, note that your observation is only true for the EM game engine. In the R'n'D game engine, robots are moving into the opposite direction after the player died or left the level, therefore moving away from the last player position.
