But of a desperate cry for help, but there was a 2D game on the NDS, in which you controlled a mech to fly through side-view levels and shoot enemies and turrets. It also had a story mode with an anime girl in orange and anime boy in blue as mech pilots. There was also a level editor, and you could transfer the levels to other DS’s with the same game using sound, which sounded a lot like internet over a phone line.

I played this so much back in the day but I can’t find the game (my mother discarded all my games from the attic some time after moving out, inc. fully functional SNES. Unrelated, I just needed to reshare the trauma) not the name of it.

Does anyone have any idea which game this could be?
