its allowed generally, but be extremely careful. Gores is a playstyle where people are conservative enough to already hate a little bit of unhook in a map, i wouldnt imagine the reactions if like vasten100 (hope name is right) made a gores map(edited)
The two reasons why there arent any tunezone maps on kog is 1) most kog mappers dont even know what tunezones are and 2) like above said gores is a playstyle that you learn to control over very long time, and little changes in gameplay/physics can get really hard to play and therefore frustrating. For example if theres some overcreative parts it often feels bad playing them(edited)
