Haven't tried the Windows version yet, but at least the Android one crashed Bluestacks 5 lol. Yeah, my phone is shitty and can't run something like that. Don't know if that could be useful info

Hmm, no idea about running it on an emulator, probably best to run the Windows version if you're on PC anyway.
About the Android version... well, it runs OK on a 2017 mid-range phone. Depending on your phone model, it may actually run fine. However, I strongly suggest playing the Windows version if you want to challenge the songs on hard difficulty!
