This is pretty awkward when you hiccup everywhere and then enemies found you and may shoot you down if they aren't zombies but some crazy persons out there...
The movement relative to mouse rotation is a bit strange but it's okay, games like borderlands 2 sure used this kind of control for vehicle system. The zombies and the ammunition amount do pose some threats but it's quite manageable at the end of the game. The field of sight does its job to help the atmosphere you want to create.
Although, the hotkeys for toggling the radar and torchlight might be redundant as they are already default on and unless there are some lethal threats to force you to turn them off, otherwise I would not toggle them.
Overall, another interesting and funny game from this game jam!
