So you call this a game? This is nothing more than trash, like some cheap smartphone game from 2016. There’s nothing interesting or innovative about it. The game takes up 20 GB of storage, yet the design and textures still look awful.

Game is ultra dead with bugs that nobody will ever fix. Ofc p2w, not a surprise, but i feel like you can enjoy it as f2p anyway. Girls aesthetics are good imo. If you decide to try this dont bother joining their discord: dead server with a mentally ill person acting like a b****, giving misinformations and free insults cause mods are not active there. Final verdict: try it if you wanna waste your time.

Unfortunately, almost everything else felt harder than it needed to be. The English translation is often confusing, instructions are unclear, and basic systems are poorly explained. I spent around 45 minutes trying to figure out how to equip an item because the game showed me the character screen once, then never explained how to return to it. The UI also has a collection of strange habits you have to discover and remember. Buttons do not always activate where they appear to, team building is awkward to find, and manual combat can send characters across the screen or waste abilities on empty space. The loot chest system is especially odd. Loot collected during missions must be manually transferred from a chest into your inventory, and I could only find a way to do that inside normal combat missions. Forg…
