Honestly, the controls were something I just couldn't really wrap my head around. I think it was always gonna be a bit awkward and limiting myself to half the keyboard to accommodate 2 player versus (something that 90% of players won't even use lol) didn't help things. At this point I'm thinking a GamePad would be the optimal control scheme, but that's not really accessible :/
Honestly, obscurity never even crossed my mind. I have a light interest in World War 2 (and y'know I am the developer) so it all made sense to me and never considered that it might be confusing to a more general audience. Frankly that's a devastatingly large lapse of judgement on my part - oops
