I think the Dreams logic system is good at orchestrating high-level behavior, and not actually great at building complex logic. Dreams works not because you can visualize your timers and variables and toggles, but because the underlying game systems are extremely well-designed and easy to control with such a system. In a sense, a lot of the difficult stuff has been pushed behind the scenes. This is not a criticism; I think it's a very good way to design programming environments for others to use.
