Having fun so far up to the 17-20 difficulty range in both modes. Game locks up fairly often on my S22 Ultra, during or just after loading anything. Dark Moon mode is pretty grindy, considering the player needs to be able to play difficulty 20+ charts with 95% score to even reveal the Hidden Song, needing 10 coins to try on top of clearing the Hidden Song 10 times to actually unlock it seems excessive. The Guardian bundle is your best deal for additional songs.

It's a nice game, cute characters and a good soundtrack... but it has parts where it's hard to follow which part of the song it's keeping beat to (something that often changes mid-song, even several times during a repeating sequence) and there's some strange lag that has prevented me from actually hitting the notes- which is a real pain if you're trying to do *good* in any way. That being said, it is still pretty fun and I do enjoy it overall. Just a bit frustrating.

KALPA is a great ad-free f2p rhythm game to pass the time with. The daily missions are a nice incentive to keep coming back, including opportunities to try out otherwise paid songs. There are even chances to earn paid currency, making it not feel as strongly paywalled as other games like it. The recent update to 2.0 really upped the polish on the game, and the tutorial was a great idea. Unfortunately, the translation is still poor. Please polish that next for 5 stars!
