Hello, the volume is going to be decreased just slightly to keep it loud enough for Hairfense's whole point, and I will fix the mouse issue as soon as I come back from school. I have received reports about the mouse issue even at the playtesting phase, and I did reduce it, but now that I have taken your review into account and actually replayed the game myself, yea, the mouse is still too sensitive, I agree. And regarding your question, no, you don't need a numpad, you can use the numbers at the very top of your keyboard like always!
