Hey fourfortyfour,
Thanks so much for playing! I'm really glad you enjoyed the time-travel mechanics.
To answer your question, there are total 7 endings, out of which one is very secret, I guess that was a bad idea for a jam cause its kinda difficult to find!
Since this was my first game jam, I just ran out of time to add a skip button (you can skip it using space button btw), but it is at the top of my list for a future update (if there will be any).
Thanks again for the great feedback!
