Despite previous comments, i thoughts its quite a creative idea to type numbers in RGB:) (except maybe intuitively each of the colours should be from 0 to 255) but probably the guys are right - normal people are not able to do it (but hey, we are all programmers here in the jam)
Actually I am not sure what supposed to happen during battle: for me nothing was happening and if i press any of the buttons i go to main menu screen
