Thanks! Do you know a nice, non-intrusive way to show the players what they're supposed to do?
For a jam game you can save time and just create a simple help menu that shows all the controls and explains the game. For a larger project a tutorial maybe. In my game I just made a popup screen that explains controls. Not very clear but better than nothing. Don't worry though your game was still pretty self explanatory after I saw the guy shoot my zombies
