ya ok let me amend that now that i played your game again to answer the 'ahhhh....which game are we talking about'
the problem is if your game isnt in full screen the upgrade icon is hard to read and the text EVEN HARDER, i didn't realize that all upgrades increased DT until i played in fullscreen. ya your upgrades are great only complaint is i wish curiosity was replaced with something to answer teh typing mini game even if it was just some sort of close animation.
