So the game has been live for a very short time and I'm already getting some great feedback on how to improve things.
It seems one of the biggest problems is people just get killed straight away on easy and don't figure out what's going wrong!
So I'm proposing the following changes:
* Easy mode: The first robot never shoots at you, so you can get your bearings and at least get a kill
* Easy mode: You can never destroy the cube your standing on by dropping your own ball on it
* Better instructions on the cube face colours (green is top, blue are sides, red is bottom)
* Better instructions on what the powerups do
If you have any other suggestions on how to make it more accessible for first time players, then let me know!
