This sounds like it would be suitable for Party Games if it were a simple map.
But if they were able to create tons of parkour maps for a standalone game then I'm sure players would enjoy it. It's just a matter of how it would work? One map might seem short, unless they timed it and made it 1 minute long without falling. Maybe make it so that every other jump is a checkpoint so players won't fall way behind? Have some type of progressive difficulty to the maps instead of having neo jumps or ladders, fences, and slime blocks at the beginning.
