Sadly, your parkour map has been Rejected!
You did not do enough with the theme to really make it stand out. The islands felt a little too small and maybe shifting focus from how you move from island to island, towards the islands themselves, would work better. I feel like parkouring on the different islands is much more effective than parkouring to a new one.
Although, it was a nice map, just not developed enough. I hope you try again, as I think you have a good chance at making an easy map.
