The Idea is to make a Classic/metroidvania hybrid, using something like CV2 as a blueprint, all Main Areas like mansions are Non-linear as all intermission stages will be Linear.
I also want to incorperate upgrades but in more simplistic fashion, basically, Stage 1, Mansion (get upgrade), Stage 2 (incorperates upgrade in design).
Aesthetic choice will be a mix between the 16-bit era and 32-bit era, hopefully I can incorporate plenty of cool SNES/Genesis gimmicks and some Neo Geo.
Upgrades will center around fortifying your abilities, Knives will be able to be platforms, Axes can be thrown into the ceiling to be a ring for whip swinging.
Of course this all sounds good on paper, but the real work into polish has to be done, I just need an engine that the learning curve isn't too steep yet capabilities don't suck, because I work and want to make progress at reasonable pace.
