Your job is to make the sliding matter, to make the sliding count. You can't just let things slide out of control. You must impart order on the sliding. Structure. Direction. Vision. Take this red dot, for example, it needs to be slid into a black hole on the other side of the map. It can be done. These maps were designed by a human and thus they can be figured out by a human. That doesn't mean it'll be easy, it doesn't mean it'll be fast, in fact, it doesn't even mean it'll be fun. Most puzzle games aren't fun. In fact, the best puzzle games are downright punishing and frustrating. You slide and you slide but you just can't make it to the black hole. That is the nature of the slide. We don't solve puzzles because its easy we solve puzzles because it's hard.
