Air Fortress would absolutely not belong in this thread because that game is an even split between STG and platforming (and in fact the platforming comes as more of a surprise than the STG)
Guardian Legend = top down + STG
Air Fortress = platform + STG
Blaster Master = top down + platform
Yoshi’s Woolly World has at least two hori shmup level sections. I feel like a shmup level or two is pretty much standard in Nintendo franchise sidescrollers now. Woolly World shares a developer and ethos with Kirby’s Epic Yarn, so the inclusion of a shmup level is not entirely surprising.
