Kawairun is a running game. You have nothing else to do but run, run, run, until you'd have enough and continue on your life. But, there is a big however, you must avoid the obstacles, the pitfalls, and try to get as far away as you can humanly possible. You can do some sliding, some jumping. And also, let me remind you, it's not just the environment that is perilous, there are several more things that you must avoid, including but not limited to bees and ghosts. You can do this run completely alone, or with friends, just to keep things in perspective.
