v1.1 is live! Your diagnosis drove the fix: the structural problem was income multiplying x2.7 per era while costs grew 16% per level. Added soil hardness per era (raw dig power divided by depth resistance) plus steeper costs and smaller artifact bursts - in simulation the full run went from ~2 minutes to many hours across multiple prestiges. Also added a x1/x10/MAX buy toggle. Would genuinely appreciate a second run if you have a few minutes.
