This game is really nice tbh, your typical card collecting Gacha, but somehow this one managed to grab my entire attention (despite all the biased negativity I've seen about it), mainly because the story tone is basically the one of an Isekai, same as Konosuba or the like, so you'll be laughing quite a lot assuming you don't skip dialogues/events, the story is interesting enough, quite a mix of Fate GO and Konosuba FD, both the Art and music in the game are beautiful too.
To mention a few features of the game:
-Stamina system (9 minutes per Energy if I'm not mistaken).
-Housing system (Pretty much like the one in Girls Frontline).
-Bond system (You can go on dates, see the past of each Doll pre-summoning, give gifts, get Stat bonuses, etc).
-Constellation/dupe system. (You can get Shards for all Dolls in the Gacha while pulling, 20 Shards = one Doll, you get a dupe, you get Shards instead, but you can farm them daily in one of the modes you get later in-game, you can only farm Shards of the dolls you own tho, so it's not exactly as the shard system in PGR, but kinda goes on those lines).
-Pity on Gacha (50).
-Theater/Archive (So you can see the cutscenes, character profile, previous Events, Doll's dialogues/voices, etc).
-Classic Dragon Quest-like combat (Turn based, you only see the enemy sprites, your characters just appear as Live-2D icons, you can see the cutscenes of the Ultimates tho).
-Farming Stages (You can basically skip them if you complete one for the first time, no "skip tickets" needed).
-Exploration and Puzzle solving based maps (You move into nodes, kinda like a rogue-like type of system, some of the Puzzles require focus or you can end up messing yourself up, specially in 2-1 onwards).
-Battle Pass, Monthly Pass, Skins, free character for the first purchase, all the average stuff when a gacha game is launched.
-No PVP (At least nor for now).
One of the mechanics that standed out the most for me is the skills sets of each character (they're called dolls); each character starts with a 4 Skill set (Basic Attack, Skill 1, Skill 2/Passive and the Ultimate), the skills use SP which is gathered at the end of each individual turn, so make a couple Basic attacks and then unleash the skills/ultimate, simple enough, things Spice up once you level your Dolls to level 15 tho, at level 15 you unlock the 2nd set of skills which more often than not will be Elemental (Fire, Ice, Electro, etc), so Mono-teams will be important later on for the looks of things, and if that wasn't enough, at level 20 you unlock a 3rd customizable set that allows you to choose between skills of the first 2 sets, so hybrid builds for your Dolls are quite vast on the long run and can help you strategize better.
So far the game feels reaaaaally F2P friendly, and the Devs have been quite responsive to any issues showing up since launch (they gave 20 summons for an error in Google Play payment methods; no one lost money, the payments basically couldn't be completed), I can see a bright future for this game tbh, I would say this game is worth to try at least, it has certain charm to it despite its slow start😌
(And there's no need to be so overly negative to a game if you're not into turn based/dungeons crawler-type generes, be respectful to those who might enjoy it and to the Devs who don't have a fault in your personal preferences).
