Never use pause in a single character game, so that one doesn't bother me. Seems too much like cheating
What I DO care about is key re-mapping. If WASD is the movement standard, can you make sure we can also use the arrow keys, or at least re-map the keys, please?
While I can use the mouse with either hand, I tend to greatly favour my left. Any genuine southpaw out there will be stuffed if forced to use WASD.
