Hey man, I get how it can be frustrating when things don’t work. But you gotta cut these sort of indie teams some slack. Most of them are something between 1-5 people working on some project that (like this one if you want to) is available for free, just asking people to give money if they feel like it. Also because of that they pretty much always have these as side projects and most of their time is dedicated to some other job that pays the rent. A lot of these people are also discovering the kinks and weird stuff in their tools as they go along.
It’s fine to be frustrated, I myself have got it and haven’t been able to run the game at all yet and yeah, it sucks. But keep this all in mind, this is not the same as <massive studio> just leaving things broken because they don’t care
