Thank you so much for the kind words and feedback! I like the different fly movement/behaviour, we could spice it up a little more! I'll need to go in and fix the ESC functionality, it quits the game (that's why the black screen comes up). The health is your bladder amount, the goal is to kill as many flies/get as many points as you can before you run out of pee.
Thanks again! We loved using the jam to wrap this one up and put it out.
