Yes multiple entries are allowed, provided they're totally separate maps. You're not to pull an icarus and give us a dozen versions of waste.
considering this is only one game mode, i don't think you have to be worried about that.
the other map (that's in dev textures on my computer) isn't even the same theme as underhanded.
this is great news for use mappers, but i hope the judges don't get too overwhelmed.
if i enter multiple entries am i able to win multiple prizes, or will only the highest prize i achieve get awarded? (thus allowing other people a chance to get a prize)
so e.g. if i (very unlikely i know) came 1st, but also got a runners up position with a 2nd map, would i get the prize for that runner up position, or would the prize be given to the person who came next in line of the scores?
