Thank you for playing my visual novel! Sorry you couldn't reach greg, I realize now that the puzzles I did are quite incomplete. And the way I coded the check to see if the questions were correct locks you out if you get any, especially the first, questions wrong. I'll create an answer section on the game page, and I'll tell you now, the first question answer is Tennis and/or Chess. That question has little to no puzzle so it really is brute force, I unfortunatly ran out of time to properly test the puzzles so I'm sorry for the frustration. The questions only affect the ending so you've experienced most of the game aside from reaching greg.
