Oh I'm just stupid, I literally beat one of the previous levels with all the bulbs off. It doesn't really make sense to me why I couldn't click it though.

I think a tutorial for all the mechanics as well as some sort of visual indicator for the bulbs you can't click (maybe a box around them or something) would go a long way. When I got to the dots, the first three levels I accidentally completed in a click or two and had no idea what they actually did, which ended up getting me stuck on the next level.
