Tig is a very harsh reviewer, probably a good thing. It looks pretty cool from the screenshot. I look forward to giving it a blast!
(Yah, I know this isn't yourfirstattempt no doubt, that was probably a emtpy box..which is the level I'm just about at lol)
But it's not the end of the world and you seem to acknowledge that fact, which is great. I hate author's who come in here and go "WTF MY LEVEL IS SO GREAT EVERYONE SAYS IT IS ITS GOOD WHY ARE YOU REVIEWING IT SO BAD"
Luckily, some authors have common sense and are bound to make better maps in the future.
