I look forward to this being hard as shit.
I could never translate my Ninja Gaiden skills into the 3D domain, but I can certainly play the side scrollers.
Sounds awesome. Not a metroidvania (thank god). Dual characters switch realms. Hypercharge attacks with optimal enemy order being a thing reminds me of Shinobi PS2. Platforming with your special attack and character swapping. Rank at the end of a stage with optional challenges.
