I know this thread is probably gonna be empty but it was released (JP) a week ago.
No waggle controls, only buttons used are A, B, or A+B.
I've been playing it since, it's about as fun and addicting as the GBA title; haven't tried 2-player yet.
Tons of cute moments that you can't help but grin; lots of troll moments also. Supposedly being released in NA towards the end of this year.
personal favorite is the bossa nova tree couple on the cloud but I can't find it
It's worth a back-up at least, you can't really emulate it due to split-second sound/button lag.
Also, if you played the original Rhythm Tengoku, some the GBA games are remastered and unlockable!
