got the time stop function working, it was easier than I thought it would be
press z to dash at the zombies, if you hit the time stop turns on, and everyone stops moving, you can turn and dash again but can't move and can't be hurt
when the time stop countdown ends all of the zombies you hit go flying
this was the hardest mechanic in the game so I'm pretty happy I was able to get it working
next is to add a dash cooldown and implement the combo system so stopping time actually makes sense
too lazy to post screenshot
