Big Picture version on Steam always crashes... but regular version under macOS 10.14.2 only crashes occasionally (like 1 in 5 times).
This was not the case with older releases under macOS 10.13.6
Anyways, thanks for a great game... I still love it, and have loved it since day one release. I have invested well over 200 hours into the game on Switch and PC (I bought it 3 times I liked it so much - itch.io, Switch and Steam...)
