Thank you for the feedback! True I didn't get the abilities working in time, just focused on customization for this one.
Mouse sensitivity is an option under "input settings," but maybe I'll bring it up on gameplay start so people with different mouses can adjust it in realtime, I notice big discrepancies between different hardware and browsers, so coming up with a preset is a little tricky - maybe I can make a calibration test where the user wiggles the mouse and I can normalize the input.
