This parkour looks very boring, and bland.
You didn't excactly keep to the theme. This looks more like a mineral parkour or something, rather than ore. Maybe if you'd combined the blocks and the ores?
Once again, there is little detail, and just like your last submission (Dice Parkour) it started out good, with those 3x3 coal jumps, then it got boring (imo)
This parkour seems more suitable for a creative parkour people advertise. It does not meet the standards of the official maps.
So I''m sorry, but this map has been declined.
