The game has free diagonal movement, you don't move in a grid, the only limit is 8 directions. I'll add the analog stick as an option later but it will still work like the d-pad.
and yes, the game absolutely needs the odd attacking control scheme, having to press a direction first and only then shoot that way would get people killed a lot later on and it would be very frustrating for them.
I'd rather ask my players to learn a weird control scheme at the start rather than give them a poor control scheme for the entire game lol.
Thanks for playing!
