Thanks for playing, and for the feedback and error report. At the last minute I lowered the music volume but clearly not enough.
I really wanted some mechanism for increasing worker count. The leading idea was designating a "party zone" where workers would go and potentially... make more workers. Unfortunately didn't have any time to explore that idea.
Sorry about the crash! I think it is https://github.com/rparrett/entytd/issues/1 and I would recommend staying clear of the edges of the map to avoid it for now.
