I like the atmosphere in this level, and the gameplay is pretty fun. What I don't like is the balancing. This level is extremely first-half-heavy, which can make it a frustrating experience to play. The UFO part in particular is really learny and still feels inconsistent even once you've learned it, and the wave part also feels a little inconsistent at times. The memory part throughout the second half, on the other hand, is basically free (provided you remember what you need to do). At least the first cube/robot part is fun.
