I honestly had a lot of fun with this short little romp. It takes a little less than an hour to beat and fully unlock the stuff, so it's not that big of a deal if you just want the sexual content. Not that it will feel like an hour, cause the rhythm meets shooter-arcade aspect is surprisingly niche on this site. The fact you can control your space ship around to avoid/shoot enemies, but can't mindlessly space the attack button willy nilly (at least not without penalty) does a great job for retaining your focus the entire way through each of the 7 songs.
The only things I can think that somewhat brings it down is the very short length/limited CGs overall (really hope for a big squeakel) and the music quality does dip a bit on certain levels/sections of songs. Most notably Level 3 and menu music was off putting to me compared to the rest of the OST. Another strange one was Level 6's tendency to drop rhythm. Despite using the same tempo for every level, I find that Level 6 consistently has me dropping the Groove combo almost at random, while I had no issue with the other levels. Besides that, this was a really good game I recommend trying out at least once.
