I enjoyed the game a lot. Everything worked perfectly fine for me. I even found (through very little effort, actually) that the mouse scroll wheel allows you to scroll the upgrades. An astonishing revelation, I know.
Yes, I'm poking fun at the comments below. They seem very whiny.
The game was good, I finished through the end of Chapter 2 in a few hours with mostly idling. The writing was also interesting and there just being a story at all puts this game far above the majority of idle games.
I very much look forward to Chapter 3. We must have our vengeance.
