Needs a late game rebalance around tokens. I'd recommend an early prestige upgrade that allows you to complete multiple "targets" per run, and drastically (geometrically or exponentially) increasing the target numbers for later levels. You'd have to rebalance the token costs on the prestige tree, but it'd make the endgame much more interesting.
Also, the prestige button should be moved to the bottom right next to Tokens, as I completely missed that it existed for way, way too long. Also, unless I'm missing something that that "Ticket" button does, it shouldn't be styled like a button.
