so i'm giving you a -1 :c
Theme: it's unoriginal since we do have a few mine-related maps (Quarry for example). -1
Build: the front part looks decent but that's all there is, you need to have a build that you can actually put your parkour onto. -1
Parkour: it's literally all floating, and you could use some more variation. next time, use other blocks like piston heads, beds, flower pots, etc. The blocks you are using are just okay, they're generic and found in many other maps. -1
honestly i don't think you can save the theme on this one, so you're best not trying to revamp it, but good luck anyway c:
