Games about parkour are always popular, but even this seemingly constant genre changes over time, and lately a special type of parkour called Mostly Only Up has become increasingly popular! In this race, all participants run, overcoming obstacles, as in traditional parkour, but there is one feature - the route goes up all the time. That is, the runner must strive higher and higher, trying not to fall, so as not to start the climb all over again. No one knows where the finish line is, just run, overcoming various obstacles and trying to do it so as not to lose progress in Mostly Only Up!
