I usually don't really write reviews, but this game is super satisfying. The card mechanics are super cool and you have to think of what to use to defeat enemies. Sure there are some modes available where the game CAN play for you if you just want to farm stuff, which is totally fine. artwork/visuals are stunning, slight grind which is giving a nice pace. Story if you're into that seems also kinda interesting or the setting in general. Overall I'm pretty satisfied so far.

The game is fun and the story is also not bad. I like the aesthetics and the main theme of the game, but was confused on some character designs. Just as an example there are like 2 defender type girls who wear a bikini instead of something more themed to space, defense or exploration. It's quite awkward to me and kinda makes me think of them as gooner bait. Why not make a bikini summer skin later on for them? I hope upcoming characters would at least fit a bit of the games aesthetic & setting.

Pretty early in playing while writing this review, but so far I do quite enjoy it. A lot of mechanics and systems in and also out of combat feel familiar, often like a mashup of various other games I've played in past years, although I don't think that's a bad thing, as it makes for pretty fun and diverse gameplay from what I've seen as of yet.
