Good idea! Interesting mechanics. I tried my darndest to get through town without being detected, but I had difficulty timing my hiding. Sometimes the poor ghost didn't want to hide even though it was right above a manhole, as well
However! I found that if I just ran straight forward without hiding at all, I was able to make it past without being detected. So happily I was able to make it through limbo and into the afterlife, even if it wasn't the intended way to do so.
