The only game that advertised in Arkea, which had no ads

It's another keyboard-based rhythm game made by the developers of Arkea themselves... It's for PC and is being sold on Steam for about 45,000 KRW. The default controls are Left Shift + asdf + Spacebar + Mouse. Yes, you play with 6 keys using your left hand. And you're supposed to be waving your mouse around with your right hand at the same time. Ah, I want to buy it... I really want to buy it.. Should I save up 25,000 PlO coins to buy that? By the way, it doesn't support Korean. That's a bit of a shame. I don't know if that ad is still showing... But if you close it, it won't appear again.
