The funny thing is we actually thought for hours as well and had other ideas that were probably more designed around the theme as you said but discarded them because they would have been way more risky in 40h.
I totally understand your point and to be honest I am probably the guy within the team who agrees with you the most.
I can assure you we do accept and value criticism. After all, it's just a jam and we all do our best to have a great time ^^.
