I notice how you guys add particle effects that fly off when a chunk gets sliced off, so I thought maybe the game could have something like blood or oil or whatever robot fluid that fling out like blood effect.

Can they also stay on your character, that would be so cool like you cut a bot down and then their "blood" is all over you, it would look cool if that said blood would stay and not disappear(except for the blood on the floor which the green flying bots would then clean up). Can we leave that then as a feature that could be turn on or off though, for those who prefer performance over graphics quality

I tried it but failed to make it look good. Might try it again at some point in the future.

I do like your idea of staining the player / the ground. That's easy enough to do once a liquid is flying.
