I played two days yesterday, and it started to dawn on me that there must be resource accumulation day to day. Some items cost 10's of coins (as much as 80), while in one day I was only seeing just a few. And really only one easy puzzle so far involving a couple of colored boxes.
So is the puzzle to just keep playing through, accumulating resources to buy what you need until you make it all the way? Or does the true puzzle reveal itself to you as you play through a few times? Maybe the things you buy/activate are one-time unlocks that give access to new parts of the puzzle, without making the puzzle itself easier?
Anyway, I love puzzle games such as Myst, and I'm a new fan of rougelikes (but not roguelites) - so I really want this game to work out.
