2 minutes to the end - ouch, that confirms it. You nailed the diagnosis: income per meter scales with the era multiplier way faster than the x1.15 cost curve, so a few meters in you can already afford everything. Rebalancing both curves now (slower coin growth, steeper tool costs) so the first prestige takes a proper session instead of two minutes. Thanks for the precise report - patch coming shortly, would love your take once it lands.
