I regret to inform you that your map is being rejected.
The theme is unoriginal, as we already have a map with this theme (Venom.) Before creating a map, please make sure the theme has not already been done before by going here: https://manacube.com/threads/parkour-list-with-theme.20194/ The build is accurate to what you were going for, and there is a decent variety of blocks used throughout.
The parkour is the main concern. It is mostly floating (meaning it isn't attached to the main build) which makes it look messy. The parkour is decently varied throughout, and varied within certain sections; however, some more variety throughout would be beneficial. I also recommend adding some more directional signs so players don't get confused. The length of the parkour and difficulty of the jumps are good for the easy difficulty!
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
