Can there be a grabbing function? Like maybe you can use the right mouse button when you are beside a dead robot body and you could pick it up with your non-sword hand and use it as a disposable body shield. Or maybe you could just grab onto those green garbage bots and be able to hang on to them, just to make them easier to destroy. :)

And also could we have a first-person mode? Sometimes when I back up to a wall, the camera goes outside of the arena and I can't see.

Cool ideas!

For the first person mode: I think the better fix is to make the camera not allowed to go through walls. It's a pretty standard third person camera thing, that I just haven't gotten to yet.
