In case you were wondering, the game will no longer be sci fi themed. A lot of what I had planned would have overlapped with Kurovadis 2, so I figured I'd do something else for this game, and save the sci-fi related concepts for Kuro.
As you may have guessed, the combat will be based around martial arts, and dbz/street fighter-ish super moves. It will mostly be fantasy themed, with some possible steam punk elements. It will still be a metroidvania with rpg elements.
And yes, you will be able to do a hadouken.
