Hey, I'm just loving everything that's being done, although I'm looking forward to the next release with the Raiden MK-II's Plasma Beam fixed.
Actually, now that I think about it, I'm not really so sure that Articuno and Moltres should be slaves, rather be actual planes if it isn't too time-consuming. Or at least Articuno, for him I'd recommend an Ice Beam that works like the Proton Beam out of Raiden III. It'd do high damage and be difficult to move, while Moltres could have weak easy to move Flamethrower maybe.
Still, either way it'd be cool, and I'm REALLY looking forward to a release soon.
Although, if I may make a suggestion as for another Cameo ship (I think I already mentioned this before), I'd like to see the Raiden MK-IIB as an alternative strategic choice to the red plane.
I also have a plane concept of my own, Alluro, that I think would be an excellent addition to the story and the game itself, although the only sprite I've done of it is terrible and needs resizing and revamping. I largely based its own storyline on the Xeno Fighters concept. Care to have a look?
