Sad to hear that my poor balancing ruined the game for you :(
If you are interested I am planning on releasing a more balanced version of the game after the jam
Sorry to hear that you didn't understand the game's mechanics, and sorry for replying so late. If you still want to know or if any body else wants to know how the saving works, here it is:
Loading a save will resat every object and paths position to how it was when saving EXCEPT for objects that are buggy (you can spot them by how they have a weird 3D effect), they stay where they were before loading the save.
Clarifications:
1) Brown rocks are the same as gray rocks.
The difference is that brown rocks come from a meteorite while gray rocks are from the beginning. this is something that I saw almost everybody playing this game not understanding and it's completely my fault for not making it more obvious.
2) Enemies spawn ONLY after you sacrifice the chicken
