The Android and iOS version of that game are free to play if you guys want to check it out. It’s a really fun game. Love it on my phone, but wouldn’t pay more than $15 for it.
Rayark is the greatest gaming company in Taiwan imo. If you really love their games including Cytus, Deemo, Implosion, VOEZ etc then you should visit their headquarters for once at least!
They sell lots of game-related products there, and they even have a VOEZ Cafe!
