"Almost painful to recommend slowing down a clicker" - best bug report I have ever gotten :) You are right on both counts. The economy explodes within seconds (era multipliers outrun the cost curve almost instantly) and I am rebalancing it now so progression actually takes effort. And noted on the ending - making sure reaching THE CORE feels like a real finale, not just a stop. Patch coming shortly, would genuinely love to hear if the pacing feels right after.
