Thanks for trying the game.
Yeah the zombies speed needs fine tuning, and perhaps a dash/charge ability. That's what I had in mind anyway.
I am aware of the mouse, one solution that springs to mind us tweening the rotation so as not to be so abrupt when the mouse is close to the player. I do intend to fix it, might not happen during the jam depending on time constraints.
I have also implemented blood particles that stick around when the zombies die. As well as some screen shake when the player is shooting.
If there is time left I want to implemented an options menu where you can enable / disable gore/screenshake since not everyone likes it hehe 😀
