It's Kickstarter page.
It's already reached its 500K goal in the first day.
An exploration-focused, side-scrolling platformer featuring RPG and crafting elements.
Koji Igarashi, the namesake of "Igavania"-style games, is leading the project, with Michiru Yamane composing the music and Inti Creates leading the development.
If funded, the game will be developed for XBOX One, Playstation 4, and PC. For the first time on Kickstarter, backers will have the option to receive actual PS4 / XB1 / PC retail discs.
You are Miriam, an orphan scarred by an alchemist curse which slowly crystallizes your skin. You must battle your way through a demon-filled castle summoned by Gebel, your old friend whose body has become more crystal than flesh.
The physical copy of the game for Xbox One, Playstation 4, or Steam (PC/Mac/Linux) will include exclusive Kickstarter-only content:
The mighty swordwhip
A super-powerful hidden boss
A Kickstarter Edition slipcase
