I love everything about this and it is literally unplayable. For a simple rhythm game of Simon Says, the input delay is too inconsistent and the windows too tight. Maybe my emulator sucked, but I could not get past the first level - and I'm a Rhythm Heaven veteran. If everything worked correctly, 4 stars, easy.

As far as rhythm games go, even the first level surprised me with its crushing difficulty (separate from technical friction.) No visual cues to match the expected button presses, frequent changes in tempo, and casually expecting syncopation to the back-beat - all tricks I'm used to other rhythm games saving for later levels as difficulty spikes. Space Channel 5 can only get away with its shenanigans with its buckets of charm.

The choreography is so goofy and detailed, with multiple dance routines programmed based on your performance. It is so simple and superficial in its game mechanics, yet Space Channel 5 still taps into the feeling of power that comes from solidarity in group dance. I absolutely love the mechanic of acquiring background dancers as you succeed and become more famous. Snatching a guitarist from another pop idol and hearing him contribute extra guitar licks to the soundtrack was absolutely delightful.

Watch a full playthrough on YouTube and you'll have a great time.
