I love mecha games but I'm super surprised by the scores and recommendations because I thought the (first) demo was really awkward to control, the shooting and melee lacked punch, and the demo itself felt repetitive. Did a bunch of stuff change from the first demo?
Yup, they took a ton of feedback to heart and improved the game significantly for the prologue demo proceeding the full release.
IF THE FIRST DEMO LEFT A BAD IMPRESSION, PLAY THE SECOND ONE, MOST CONCERNS WERE ADRESSED VERY EFFECTIVELY, AND YOUR SAVE DATA WILL CARRY OVER TO THE FULL GAME.
