Thanks!
I should have put in a simple splash with controls and instructions on how to play. Since I didn't have time for an actual tutorial anyway. Well, now I've added controls into the description.
Now I also need to create a spec for the virtual machine that control robots - I've managed to implement almost 40 opcodes, but failed to create some examples of really smart firmware.
With all these artifacts present, you can actually play that game as a local multiplayer - everybody will create their own firmware, upload it and then let the bots fight each other without human intervention... just like in RoboCode/Omega and the likes.
