Really good game would recommend, so far I've only gotten every ending but 3, not sure if number three is harder to gete natrually or i'm juust making a mistake.
Spoilers for ending 3:
-----
Step back instead of coming closer to Maverick in the lake, then Do what Camden says when he tells you to run, then when Maverick asks you to stay after he saves you from the deer (this choice will come whether or not you go back or stay with him in the corn) say No and that should give you ending 3 :)
