-This level is terribly large. The size of the level causes giant graphical glitches. Add some walls, and make the entire level at least half the size it is. SRB2 causes glitches due to having to render so much at one time.
-The level is empty. I couldn't find much, if any, Rings. There are no obstacles or challenges to get to the other flag. It just matters where you are. Try making some parts have peppers and sausages, which you have to run around and jump over. Make the crust rise up.
-Where are the flag locations? Most flags are located in a fort-like area. I couldn't find any.
-Don't enter a custom level in another level's slot. It messes up with people playing coop, match, and other modes. Try slot A1. (level 101)
