Oh wow, thanks so much for playing! And thanks for supporting the Ukraine Bundle!
All endings are based off of how many right answers you get.
Ending 1 - Answer all questions correctly
Ending 2 - Get a few questions wrong
Ending 3 - Get all the questions wrong
I don't currently have a walkthrough with all the right answers. But now that you've played it once, it might be easier to know which answers are correct. I hope this helped!
