I don't know much about Muv-Luv but I recently checked Project Mikhail on Steam and it seems like a complete shitshow judging by reviews. I am just confused, how hard can it be to make a semi-decent EDF clone? You already have good mecha designs, just put them in a game that's not complete jank and you're golden. Even Nitroplus managed to make passable AC clone recently, so it should be doable even for an indie studio.
