Haha nice one! You're not old (and I'm not trying to be judgemental, but this is the truth) , it's just that 70% of the people are sensors, meaning they see familiar patters they learned in the past, and easily understand what to do. The other 30% of the people are intuitives, meaning they see abstract patterns they never seen before, and easily make sense of it. The game never aimed to be conventional, or obvious, just a bunch of metaphors unraveling as you progress. And you're right, I put some more hints and clues in afterwards; make sure to check back once the rating period is over! P.S. all my intuitive friends figured out what to do.
P.P.S. I already have your game pinned, will test it out soon ;)
