Hey o/
I love the theme! I remember playing that game and having an amazing time, good job finding something original and interesting as your theme. However, as Spiro said, the build is mostly pixel art portraying some player models. I get the idea, but these player models limit you in so many ways. When I first saw the title of this map in the forums I expected you to build a level from Geometry Dash in 3d. That was the first thing that came to mind... Also, again as Spiro said, your map is way too long. Insane difficulty is 120-200~ jumps.
Prepare yourselves, this most likely to get rejected because it's way too long. if you guys would like to resubmit I'd love to see a level from the game built into a parkour course :3 Nonetheless, I wish you luck with your submission!
:)
