This game is awesome. The way you can customize your mecha is so cool.
The gamplay is fun except when it gets difficult because it can get frustrating due to all the things happening, like if it was a bullet hell and the camera not helping.
The story is very fascinating but the highlight goes to the charates. They are very well written and they so cool and interesting to hear them and read their background.
What combines all above is the Arena mode. The best thing in the game. You can see the cool mechas, fight them and know them.
