"Delay" I think that's a cheat.
...it acts just as my normal SpaceKey would. It's just that AHK sends the keys for a too short time without delay.
i.e.
send, {Space};would sometimes result in shoot, sometimes not.
Think if that's really considered cheating you'd have to bann certain Keyboards and other hardware related things.
imo it's simmilar to not considering /arrows cheating (because then a larger monitor with better resolution would also be cheating).
I think cheating would start, where somebody uses double pressed Space for one key to get a Liero like rope or something.
I tried that [
offline] out of curiosity - doesn't make you better. I sometimes see people using things like that failing a lot of times =)
