Hello Matt!
I am here to give you my review of the map! Please remember that I am not a map judge, and my opinion doesn't affect the map being accepted or rejected. I'm just trying to give helpful advice on how I think you could make your parkour map better!
I'm sure you know of the three main criteria on Manacube Parkour; Theme, Build and Parkour. I'll go through each of them thoroughly in this reply!
Firstly the THEME of your map. I believe your map submission has an original theme, as there are no maps made of specifically ramps. Good work coming up with an original theme!
Secondly the BUILD of your map. I am a fan of the build! It's simple, yet really cool looking in my opinion. I'm not the best builder out there, and my standards for builds are quite low though, so I'm not sure what the Map Judges will think of the build. I think it's simple, but attractive and it's easy to see what you were trying to build! Nice work!
Lastly the PARKOUR of your map. Thank you for letting me fix up some of the Parkour with you, I hope I haven't ruined your course doing so! After a devastating session of nerfing your map, I can now happily say that I think it fits the Medium difficulty you were going for quite nicely! The parkour is also decently fun, the jump and block choices used were both fun to parkour on, and MOST OF THE TIME fit the map's aesthetical appearance very well! Your map also fits the length for Medium maps, even though it is on the longer side, and NOW has well thought checkpoint placement! Good work on the Parkour, thank you for letting me help!
It's going to be a +1 from me! Good luck :)
