This was really fun, but unfortunately I could not finish. I ran into a bug where all upgrade buttons became unclickable (sometimes (?)) and flickered (played their hover animation over and over). It got to a point where I tried to refresh the tab, but that lost me my progress. This happened immediately after maxing out the very first passive generation upgrade (might've been "thought"), and I wonder if the button disappearing had anything to do with it, as I think I might've hovered it as it was removed, or something like that.
But I did really enjoy the game. It was well put together, and all the flavor text was really interesting. Additionally, it was only ever pleasantly grindy - getting through a dry spot was always rewarding, and they never lasted long. Not interested in doing the grind again to get to where I was though, unfortunately. But I might consider it another time if you manage to fix the bug.
