Hi! Sorry you couldn't play it :(
It's not really "broken", it's just that my control scheme is really bad (I just changed the keys from something I made with a controller in mind). Basically, Q and E act like bumpers on a controller that you need to press in order to move diagonnaly. The moveset is: Q+W (Q first, then W while still pressing Q) to go up left, E+W (same E first) to go up right, etc.
I guess it shows that I need to let other people test what I do sooner, to be sure that it's not too strange :)
thanks for your compliments on the menus though X)
