Hello sillllllllllllll,
Unfortunately, I will be Rejecting your map.
The theme is original, there are a few snake themed maps, but none exactly like this. The build is good, it is well built and nicely detailed.
The parkour has good variation in places, but there are a few quite repetitive sections. For example, at the beginning it was mainly ladders, normal blocks & fences, and there were a few sections of just ladders. It would be great to see the variety be consistent throughout the entire map.
I also found the parkour quite confusing. There were some areas, especially around the middle section that were quite confusing, as there isn't an obvious direction on where to go, and aren't any signs indicating how to do so, I would recommend trying to make the path of the parkour a bit clearer as it is easy to get lost throughout the map.
The length and difficulty are good for an expert map.
Thanks for submitting your map! I hope to see more maps from you in the future.
