Take a look at Hauntii, an upcoming Unity-powered single-player adventure game currently being developed by Moonloop Games. Hauntii promises to be a twin-stick shooter and features a beautiful hand-drawn art style that helps create a mysterious and other-worldly landscape.
The game's story follows Hauntii, a curious ghost who has just arrived in Eternity, a place that exists outside of space where all souls eventually end up, trying to uncover details about his past life and learn about his demise. The developers state that the game will have a relaxed, contemplative mood, open-ended level design, and high-energy shooting moments.
