Thank you so much for playing :D Really neat to hear folks experiences and honestly is the best part of this for me, so again thank you! A few hints for you.
1. Knowing how to add time is VERY important to completing the final ending to win the little competition, knowing how to add time is a must.
2. The maze is important, but not to completing the four numbers, but having knowledge of this could help at some point.
3, The BF ending only really only tells you that it is known that you BF the puzzle, it was just something funny I put in after a friend did that and beat the game that way :P
You're on the right track with the radio and the four pictures... maybe just check in on them more :)
Seriously thank you again for taking the time to write a message :) Very cool. If you get the forth number let me know would love to hear about it.
