I enjoy the novel introduction of tower defense to gacha and think it's a good way to make use of a large team of characters. There's also plenty of really cute designs and Utage is probably the hottest thing this side of the google play store. The edgy setting and story don't appeal to me at all so I ended up skipping the story but I had a good time grinding out the stages. Eventually the lack of a skip button or higher replay speeds just started to drag and the chibi sprites don't hold up well enough in the post-blue archive age. I am also a massive brainlet when it comes to tower defense so a lot of the gimmicks could get pretty frustrating. Definitely still in the upper echelon of gachas and worth trying if you're in the market for them.
