Thanks everyone for the playtest!
Sorry for the missing manual - haven't managed to squeeze that into the jam. But I've updated the description today. It has the controls and a background story (how silly it may be).
The main game loop is to move around, pick up energy crystals and cyber-sneeze to infect enemy robots with your firmware.
And the main problem is the energy distribution.
It is accumulated in the receiver while you walk. That energy protects you.
You need to stand still for a second or two to sneeze. Otherwise you will not infect anyone.
