the game is fun, but I've been stuck for over an hour on level 4 (the one with a green power source and a yellow power source but 2 yellow outlets) because there is an open line with the green power source. The tutorial didn't really explain what those were or how to solve them, so I'm at a complete roadblock. I'm giving up on it for now since I have absolutely no idea what to do from here. I don't think I understand the goal of that level at all or what the green power source is used for there.
I dislike the feature where you need to spin tiles around multiple times sometimes for the power to connect, but that might be a bug.
Besides those problems though, the game has been a really fun puzzle, and really difficult at that. I don't at all mean to come off as rude here, I'm just completely stuck and confused. It is a good game.
