normal amount but thinking maybe 1/35 scale figures 
Oh, very cool! We've seen folks use Pulp Alley in a lot of different scale, but I don't think we've seen 1/35 yet.
If I was going to do 1/35 I'd bump the table size up to 4'x4' or maybe 4'x6'. But I don't think the movement/ranges would need to be adjusted.
Really, I just suggest going with whatever table size looks/feels right and you got a good eye for that kind of thing.
I'm excited to see what you come up with.

HAVE FUN
