Having owned a couple of versions of bopit, I'll say this mostly replicates the experience extremely well.

I really like the twists such as the extra levels and changes in command, and the fact that the game has progressive unlocks.

My only requests are firstly, it'd be nice if you had actual human voices for the commands, rather than relying on screen readers or other installed voices.

Secondly, it's a shame that the commands tied to extra keys such as flip it, spin it etc are enabled/disabled via the main menu, rather than being used to create different challenges, ditto with the speed control, though balancing customisation and progressive challenge is always a bit of an issue.

either way, great job, going to look forward to see how this gets expanded, either with extra modes, or just with more background rhythms and sounds in the future.
