Well first off: we have a lot of levels like this already made. It's useless to put the black emerald in your level, it won't do anything unless the wad has it's own game.dta. If I were you, I would not have released this level at all, seeing as it is quite cramped (even though it's supposed to be a small room.) Are the star walls supposed to be sky? If so, you have to make the thok barrier height lower than that of the floor. The level for what it is isn't bad. Infact the only thing that makes it "bad" is the fact that other people have made many wads such as this.
