Will game saves be wiped at any point during development?
Our intention is to never wipe saves or make them incompatible with previous versions of Slime Rancher. While it is possible that given the unpredictable nature of game development a situation may arise that could affect save files, we will do everything possible in order to prevent it.
It's worth noting however that updates may still affect save files in manners that are undesirable such as when we released the quarry and some players discovered they were now inside mountains. But all of these issues should be fixable.
