To start of: I really enjoyed this. There were some creative riddles and the likes but it was not mainly the assignments at the gates that caused this.
I do feel I should give a compliment to Kyphis for posing interesting questions for all.
What I enjoyed most was the feeling of coherence in a way, people being at the challenger unable to pass sharing probable online times, sharing experiences of what was to come if gates were passed. Quite frankly, the 'mood' reminded me of the good ol' days.
That being said, there are some points for improvement:
In my opinion the best riddles have but one solution. I encountered some riddles that had a multitude of possible solutions, the 'correct' one being arbitrary and not necessarily the one fitting best. This was slightly frustrated. If you make riddles that have alternate solutions you might want to consider counting them as correct if fitting as well or beter than the intended solution.
A much smaller issue was time zones, I think it was Windy whom was only able to log in for a few hours a day. On a few days these hours happened to be situated in the middle of the night CET, which was inconvenient. I can imagine different challengers had their online time in different time zone’s nightly hours.
I was surprised by the amount of online time quite a few of the challengers/gatekeepers put in. Thank you for investing so much of your time into an enjoyable event.
