Developed by Catstudio; who's self-proclaimed forte is getting Tower Defense games right, ironically is most revered for this game. Anyway; you manage a cafe run by cute anime girls. The appeal here is that the anime girls you manage are actual anime characters....like....the protagonist no one ever talks about. You tap on their heads to give them a pat of approval that will increase their speed (Don't overuse it, they'll hate you for it). You start off hiring palette swaps though, so don't expect to have the original Saber on your ranks early on...unless you get lucky ofc.
Its more of a management game, but there are no paywalls like waiting for 5 eons to cook fried chicken; its more like Simtower where the day is like...10 minutes. So you can have fun with it whenever you want. Part of the appeal is also at the arriving customers which may consist of characters like Lelouch, Mami, Shimikaze, Tomoya, etc. but there are some unremarkable customers to populate your cafe as well.
The game has IAP, but its generous at giving away premium currency at the 5th and 6th days so long as you log into the game with an internet connection at least once a day. Not only that; but you also get an Ultra Rare 5 star original maid per week....provided that you do the aformentioned internet thing ofc.
Oh and you don't need an internet connection to play. IF YOU HAVE CLEAN MASTER OR ANYTHING SIMILAR; THE APP WILL DETECT THIS GAME'S JUNK....THIS "JUNK" IS ACTUALLY YOUR SAVEGAME...DO NOT LET IT CLEAN THIS APP'S JUNK
