Probably way too easy as a rhythm game, I'm not that good at them but I was able to have some fun with this, but as far as I could tell there were no higher difficulties to select so there's nothing here if you were expecting more. It never really challenges you by quickly alternating between the left and right buttons, it's only ever the same one button about 3-5 times in a row. There's also only 11 songs in each version of the game, I think I completed whatever story mode there is (you can skip through the dialogue fast by holding L) because I eventually got to the credits and unlocked Shangri-La Shower but I don't know how I would unlock the last 5 songs that were just solo songs or alternate remixes (those remixes do go hard doe). The songs actually are full length though, that's probably one of the gimmicks they sold this on. I don't think there's much wrong with how the 3D models are modeled, but the shaders or lighting or whatever looks really bad here (or is it a complete lack of shaders?) and it makes the graphics look really cheap. There's also some bonus challenges like to reach 600,000 points in a song, where when you reach the target score it abruptly ends the song and it's kinda funny. I didn't know how to unlock more than 5 of these challenges though. I'm making a guess the VN sections are nearly identical across all three games, there's so few unique songs in each game that it's really cheap for these to have been any more than one game really. Lastly there's a mode where in the club room you can change the 3 girls' outfits and have them say different voice lines you unlock, but I don't really see the point because it's not some sort of poser or viewer mode, they just stand there and it's just a closeup of their face and torso where you can't see their full bodies when you make them speak random voice lines. I'm not any good at SIF, maybe 9 buttons or the touch screen is too much for me so I was curious to check this out for being different but it's just not really worth even playing for 1 hour unless you like emulating random obscure franchise releases for the sake of it like I do (tbh I would've played the idolmaster taiko games first but they don't work past the title screen in Vita3K). Apparently these devs made the Hatsune Miku Project Diva games on the PSP but from what I saw those are actually liked and they just massively dropped the ball here, I think the dev studio shut down not long after these were released.
