I am currently mountain 105 and i've noticed 2 things on browser (chrome). 1. all of my ores are currently moving in slow motion as I easily average over 1K current ores which honestly not much I could see happen as 90% of the time they are still in the air but definitely slows down gold production. The second thing I noticed is that souls take FOREVER! I am only waiting on soul upgrades and upgrades that require over 10 mithril. Yet again I understand this is an incremental game but it seems like it takes forever just for 1 soul, and I need up to 3 souls just for 1 upgrade. thank you for understanding and very great game overall. <3
