Hello! I've played your parkour and wanted to express my thoughts about it.
The build's theme is
quite overused and doesn't impress much. There are a lot of maps already made with the theme you were going for, such as BiomesPK (but that map is a goof so we don't count that trololo). Your map also seems to
lack a main build that the parkour can build itself out of, which
makes it seem all over the place. If you wish to have your map accepted,
you should come up with an idea for a map that hasn't been created yet!
The parkour is also quite
boring and repetitive, with mainly focusing on
block and ladder jumps. You should
try using different block structures that can alter the gameplay of the parkour, such as
slimes, heads, piston heads, flower pots, etc. There are places where you can just
skip the parkour, and things like that should be patched up, that's why you
get other people to playtest your map!
Overall Noah has put it nicely, that if this was 2014, the map would be accepted. Unfortunately that isn't the case now. If you want to build a map that has a higher chance of being accepted,
I'd recommend looking up to maps that get accepted nowdays. That way you could get a
more broad approach to making the main build, as well as the pk for it. I'll link a guide below that may help you out if you wish to continue.
Thanks for submitting your map and happy building!
