I could have sworn that the first time i tried the tournament editor, i was able to click in the True/False fields to change their values? Now it seems locked per creep type. Like, Green Goblins go reverse (as its set to true), and no way to change it.
Did you change this or is it something on my side?

It's always been that way. You can change almost anything, except for a few things.

People already know that if they see the green goblins that that enemy will go backwards. Allowing people to change that might make for a confusing game.

sounds like it would make more room for creativity, throw people off guard by making, say, red rockets go backwards and green goblins go forwards, or something different like that

Awe so then we can't make it so that all waves come from the red spawn except green, which would coime from the green one?

Well, If you want to be able to make things go backwards that normally woulodn't go backwards, I can make that happen. It could be confusing for the player because I don't have any warning that the next wave is a backwards wave.

i think that we should not be able to change the backward, simply because, like sparti say, this would be confusing,
we could not know if they come bacward or not
