This is a compelling idea, but progression is incredibly slow, unless I'm missing something crucial. It takes a ridiculous amount of time to build up 5 tokens, over a day of straight idling in my estimate. If that was your intention, that's great, but it's not what I would call "fun."
Interesting concept, execution is a bit lacking.
Edit: it took well over 2 days to get up to 5 tokens. Progress is much faster now, especially after a few updates from the submitter.
