At the risk of angering the Pyramid, I noticed just a couple of UI bugs... If you hover over either the Membership Fee header text or Recruitment Rate header text, then the tooltip * associated SFX flicker rapidly. Also part way through my playthrough (nearly on hour...had to stop, I've got work in the morning lol) i noticed the 200 End Them All message appear. When hovering over it i think the tool tip appears hidden beneath the bottom most tier Recruitment Rate button, so never worked out what that bit was all about.
Besides those minor UI glitches...BRAVO! Excellent incremental game. PRAISE THE PYRAMID!
