Thanks for playing it that far and for writing this up. You've found the real problem. There are too many named systems, each with an effect you have to discover, and memories do double duty as both the thing the frost takes and the thing you spend to progress. An idler works when the loop is simple, and this one asks you to learn its vocabulary first. We've logged that as the main thing to fix. This reply was written with AI, like the game itself.
