Parkour is an obstacle course game that tests players' agility by requiring them to run, jump, and climb to get from point A to point B. The courses have different themes and range in difficulty from easy to insane (extremely hard).
If letting gravity take its course is more your style, there are a variety of dropper maps as well.
Currently on Season 2.

1.8.9 is the recommended version.
1.9 and above is not recommended due to 'rubber-banding' on piston heads.
1.12.2 can work fine, but can be a little bit glitchy on ladders because of their larger size, but won’t have the same issues as later versions.
1.14 causes issues with water and glitching on piston heads.
1.15+ makes many blocks very glitchy and the parkour virtually impossible to complete. The main issues include water, heads, snow, and ladders. It is not recommended to play in these versions.
