Ghost Song
developed by Old Moon Games.
An actual (super?) metroidvania that’s been in development for a few years, and is hopefully coming out at the end of 2015. While it definitely looks like a modern Super Metroid, the game is also supposed to borrow elements from Dark Souls. No hand holding with the gameplay. :) The mix definitely gives it a great looking atmosphere.
