Well, I paid a few dollars for the game like it's one cheap stuff but that the time it came out on Android, the cost is a little bit more than a standard $2 snack you can buy like a burger or some sort. The game has 30 songs for the first chapter with the second one coming soon in the future. Will it end up like Cytus with tons of songs coming in in the future? Who knows? Plus, it has three characters with different styles to choose from although some outfits are going to be kind of disturbing and one of the characters is a little kid.
Control-wise, you have two control methods to choose from and it already took me time to get used to both control methods. One is horizontal and the other is vertical. Certain songs are taken from various Japanese music and sound resources like Dova Syndrome, Musmus, Pocket Sound Effect, etc. which are the resources indie game developers can take music and sound effects from. It seems that many things have changed when it comes to Japanese indie games with new effects taken from those sites, new existing music anyone can use in addition to the game's originals, etc. The BGM for Stage Clear in this game suits the video intro/outro or game's Title/VS/Decision/Challenger screen better.
The third flaw regards the delay/skipping of the music that affects the timing and I don't know if the game works on my older Android device or not. Raycrisis didn't work at all on my main tablet but it worked on other Android devices I have.
From my gameplay videos, the game's played one-handed but it can be tougher that way when compared to doing with two-hands but at least, it is a fun game when compared to Dark Witch Episode Music Rudymical whose game rules are quite rough. As of this time, I don't know what the rest of the songs is like but there will be more gameplay videos from my channel in the future. Also, the Steam and Switch versions will be released at a later time.
