Outdoorsy Pandemic Simulator. You play as a bear who is deathly ill. Maybe it was something in the water. Maybe it was something you ate. It doesn't matter though, you're going to die. What counts is how many other bears you take down with you.
Use mouse/WASD to explore. Once you are ready to shuffle loose this furry mortal coil, press "P" to do what it is that bears do in the woods, one last time. If any other bears come in contact with your "leavings", they will become infected and spread the virus further. Infect as many bears as you can.
This is a "one-shot" game, so plan your attack carefully. Once you go, you're gone, and can only watch on as events unfold.
(There is currently no reset button, sorry.)
Install app on Mac, launch file. Easy, right?
