It isn't working for me :( I'm just suck on the "Press A To Start" page. This looked really fun so I'm kinda bummed. Looking at the other comments it seems like it's just a me problem. So no need to worry
Yes, sorry! It does require a gamepad. I couldn't think of a good alternative control scheme for keyboard. Maybe using the mouse to aim? But that might be too accurate in comparison to an analog stick.
