I've noticed some weird inconsistencies.
You can click and drag to scroll the buildings menu, but not if you are mousing over a building at the time, otherwise you have to use your scroll wheel.
The scroll wheel doesn't work for the items window, you have to either click and drag while not mousing over items, or use the scroll bar.
But the scroll wheel does work on the Research window.
It would be great if I could use my scroll bad on all windows.
My initial plan was to complete all the quests, and try and get all the achievements. I'm not up to quest 25 and have 70% of achievements, but progress is basically at a stand still, so I'm going to stop. However I think this is a nice and simple little incremental. I had fun.
Good start to an idle game. The buggy achievement screens needs some work, and I found the box with Produce Energy and Attraction kept moving depending on my gain per second of resources, which got annoying quickly.
