I assume TL don't put in a confirmation for spending gems because they want us to spend more gems (and hopefully buy more), which I can understand in an established game like Restaurant Story. But it puzzles me in Castle Story, where they are clearly still balancing gameplay (changing max energy level, crafting ingredient amounts, etc.). You'd think they would want as accurate stats as they could get regarding what causes people to spend more gems (which I'm assuming is the ultimate goal of their optimization... finding a balance between players buying a lot of gems to help with gameplay, and players leaving in frustration because it's become too tedious.) If players are falling into "gem traps" as often as people here say they do (and I certainly do), TL is getting awfully skewed usage statistics.
Just the optimization nut in me, I guess.
