Played way too much of it to justify a score lower than 3 stars, plus they've FINALLY added an auto-play mode 3 years after MLTD has done it. They could put a bit more effort in the cards' art (just look at their counterparts, Million Live and Shiny Colors) but a few Cinderella Festival SSRs have looked pretty good. What's bumming is how the art quality drastically drops from a limited card to a permanent one.
The characters are cute but most of the new songs feel pretty uninspired, especially compared to the earlier event songs (pre-2018). The gameplay itself is fun but def not as challenging as other rhythm games out there, with Master+ and GRAND mode being the most challenging songs as for now (WITCH mode is just annoying as fuck).
The gacha system remains garbage, and that's after playing almost 10 years of mobage gacha (well, if you can count Kancolle as one...). At least they have the Memorial Gacha banner which is a godsent as the pity doesn't expire.
