Actually, it's not just you. At first I thought maybe it was a language barrier for some people. But I got a native English speaker who should have been able to get all the references to try it, and he gave similar feedback, saying it took him a lot of tries to guess some of them. So I would probably need to rewrite them to optimize the experience. Admittedly, I wrote all the riddles at like 2 am in the middle of the jam, so I was quite tired, haha.
