As of this writing, the game should be out in IOS & Android in June 14 & June 15 respectively with the Steam and Switch versions to follow later. It is an indie game containing resources taken from various Japanese music and sound effect resource websites. Those sites are super-okay to use the music, sound effects or both for whatever content you're making like a YouTube video, public performance (Some comedian happened to use some music from those sites), indie game development and so on. Just make sure you credit the sites you're using those things from although commercial use can be a challenge. Prior to the game's release on IOS & Android, there was already a beta-testing campaign for IOS version. I don't know if that existed for Android version as well.
From what I saw of the gameplay videos, the style is quite funky looking and the gameplay may probably remind you of the other side-scrolling rhythm games where you have to hit those things to the music coming at you. Previous games I know of include Eat-beat Dead Spike and Legend of Dark Witch Episode Music: Rudymical although the latter is ruined with grunting to the music along with lack of other character attacks.
The Stage Clear BGM is surely familiar for me as it is one of the tracks taken from some Japanese music resource website. I don't know where is it taken from exactly but I surely first heard it from the intro of some Voiceroid Let's Play/Game Showcase videos. They look professionally made but music like that is quite indie-ish. There may be western sound effect resources I know of like freesfx.co.uk, freesound.org, etc. although I feel like there's less guarantee in using those sounds from freesfx.co.uk as certain sound effects are obviously used by companies in addition to indie content makers. I wonder if those sound effects are illegally uploaded there or something but it's best not to use them out of my doubt.
The game has tons of characters to play as and there will be bosses in the middle of the songs to deal with. One downside is that you can actually tap them that causes them to look disturbed. Another downside of the game is the developer name in which the word, Pero, may mean, Lick. It's a disgusting action from the sound of that word and people have been making such comments like that when it comes to some child characters like Platinum the Trinity from Blazblue franchise. I bet that there may be one of the characters from this game who behaves like that and one of the home screen quotes has her mentioning something like some service or whatnot. What were they thinking when they came up with the disturbing team name like that?
Anyway, this is one game I'll be looking forward to once it comes out on mobile although the name of the developer group is a controversial one to me. I don't know if that is an insult or not but there are better names to look through like Muse Software, the company that made games for past computers although it no longer existed in the past and of course, Muses from Persona 2 although they are produced by a bad guy so the story is a dark one.
