So I've already been working several months on this prototype.
The game is called Swansong, and it's your typical Metroidvania with RPG and rogue-like elements.
My biggest infleuences were old Prince of Persia and Dark Souls
The swan song (in ancient Greek: ????e??? ?sµa) is a metaphorical phrase for a final gesture, effort, or performance given just before death.
So far what's implemented:
-Platforming mechanics: run, jump, wall jump, wall glide, ledge climbing, ledge hanging, drop off a ledge, ladders
-Basic combat system
-Basic In-Game menus
-Character Selection menu (characters can be customized: tribes and heads)
