Hi so I made a level with delta Sonic Worlds... looking for some feedback on it!
Also how do I add more levels into it? Or align sprites?

A little background on the stage. Its intended on being early in a game, so its supposed to be easy. Want to give it a neo green hill/aquatic ruin type theme.

Heres the link: https://file.io/u77JMo

Also how do I change the level background sky?
