Hey Tree, I'm putting your map into reviewing because
The theme is original since there aren't really any grave maps, and building yourself inside it was a really nice touch. The build is detailed and attractive, it's a good size for an Expert/Insane map and it looks good, good job. However the parkour is not good, it's a good length for an Expert but parts of it are way too hard for an Expert (Insane jumps) and most of them are really annoying (a lot of headhitters, cobwebs, etc.). Remember that the goal is not to make the player struggle but to create a challenge with fun, difficult parkour. Some checkpoints are Insane and some are Expert, basically.
So you have till the end of the month to fix the parkour (write in this thread if you have) and if it looks good I'll be happy to accept since the build and theme are great.
Thanks for submitting, would be great to see more maps from you!
