Hop Step Sing! Everywhere!

If you view this like it's sort of a collectible of an indie band that you've been following, it's ok enough. It's basically the same idea as their singles on Steam. For a roughly similar price, the idol comes in and sings one song for 3-5 minutes, then leaves and it's over. No extra content. You shoot slimes for a bit (very similar to one of the Mixed Reality demos) while she's singing. Honestly nothing all too wow worthy but I am sort of a fan of this group prior, and it's ok enough for me.

But to be perfectly honest, inside of Meta Quest store, it is really uncompetitive. And especially if you've never heard of this girl or her band, nothing here will really convince you either. Moreover, while their other singles on steam often has full environments, multiple transitions, etc., in this app she just sings in your dinky room (which is kind of a problem for just about every MR apps/games out there). If you're not specifically looking for this kind of experience, but just looking to get something interesting to play, there's a very long list of titles that you'd go through before you get to this. Even for me I wouldn't really recommend this to anyone unless they're tried-and-true fans of this specific character/band.

And lastly, Mikasa looks very different from how she usually looks elsewhere and I think that is a significant miss. She should look more like the Steam version (or rather, her live concerts).

If you're somehow almost convinced by this app and found the experience just a bit more wanting, maybe try their other content on Steam (also VR).
