don't know how many of you realize, but when creep is on top of unbuildable tile, there always is a one tile gap that creep refuses to grow on... this makes it so that if you don't build your hatchery in ZvX towards the bottom, creep will never spread and zealots will be able to run through the gap where you aren't able to build creep colonies
however there is a solution commonly used in low money maps, and i've implemented it on the attached version of FPM i made. there are certain doodads that are unwalkable but blizzard forgot to make unbuildable (picture 1), though you can't build on them anyways because they are unwalkable. this makes it so creep will grow further down than usual (picture 2)
1, 3, 5, 11, 9, and 7's chokes are fixed with these tiles
also, i've implemented another low money map making trick where probes/drones/scvs spawn on top of the command center at the start of the game, however workers made after will still spawn where they normally spawn. (picture 3)
map is unprotected so do whatever if you want to use it for league
