Of course, a lot of this has to do with the type of game each person usually plays. In the ones I play, W, S, A, and D are used only for movement. When I tried your game, I tested the arrow keys and thought it was bugged or that I didn't have any options available. I ended up pressing several keys to realize that W and S were the ones selecting the options. But that's not a problem... your game is very well structured. I was just sharing my experience since it might happen to other people too. Good luck in the Jam. :)
