Hey TheSalemGamer, sorry to tell you your map has been rejected.
The build is decent, it looks like the house from Up, but it's a little simple and like was said above it would look better if there were more balloons, imo. The parkour isn't great, it's not very varied since we see a kind of jump once and then never again in the map. It's also pretty short for a Medium. The main problem is obviously the theme since there is already a map with the exact same thing (Up).
Thanks for submitting, I'd love to see more maps from you!
