That was a lot of fun. I enjoy the elements of both mech combat and having some more relaxed story (dating sim in this case) elements mixed together. By the end, I was a cyborg freak, but that's OK.
I will say that the enemy's AI being simply CHASE! made combat feel like I was always running, despite the story being about putting the enemy on the run. While I felt powerful enough, I didn't get any sense that the enemy was ever bothered.
I opted to use the semi-auto aiming since I figured that fit best with the in-world dynamic of her being the gunner while the player being the main pilot. The fully autonomous seems a little too cheaty and the manual was quite difficult to hit the helicopters and soldiers with.
I look forward to progress from this if you ever get back to it. I always love more mech games coming out, no matter what kind they are. :)
