Rusty Flesh

Rusty Flesh is a sci-fi horror puzzle platformer for the Game Boy Color where you switch gravity instead of jumping (guess you could call it a VVVVVV-like!). Explore the different areas of a derelict spaceship putting together all the pieces of its lovecraftian mystery, and enjoy its retro-futuristic aesthetics.

In the near future, Earth has become a wasteland, unfit for any kind of life. Nations fell, and big tech corporations seized power. They had been getting ready for this. They built massive spaceships where a few chosen ones would travel for hundreds of years, looking for a new home. The Grampus was one of those ships… but something went wrong.
