Honest opinion: Gameplay mechanics are really interesting, visuals are quite good. If you ever wanted a “pokemon but without keeping it kids friendly” game, this might scratch that itch just fine.
I didn’t got deep into this game, but it has a noticable lack of direction. The game doesn’t tell you what to do aside from the basic base building; but I like it.
Oh also, it’s quite buggy in this state and crashed occasionally; so you might want to give it a few more updates before buying if you dislike that.
