A few days ago I had created a custom level with the theme of being very, very slow (for frustration's sake, not fun at all) Today I got a comment on the level saying it was hidden because it has no music (it does not have music so this is right) But also an email saying the level was incompatible with the game. Are being incompatible and being hidden the same thing? If not, why was the level deemed incompatible? If it was because it was really bad and troll-y I undeestand, but I couldn't find a rule about that in the guidelines.
