1. Troll game / You put absolutely no effort into the game / Your story actually managed to anger me.
2. You only mildly annoyed me / the effort was poor, not absent / I can't actually tell if you're trolling or not.
3. You're trying and I applaud that, but it's still not very good.
4. The story was ... okay. / It was not very well made, but I liked something about it.
5. I liked it and you did a pretty good job.
6. I really liked it, you did very well, and I can't find more than a couple mistakes.
7. It's not perfect, but in my eyes, it's getting close.
8. Either I'm blinded by something you did that was really cool or the quality of your work is just that good. (Or, quite possibly, a story is--in my opinion--the best of what it could possibly be.)
