Souls in Stone
You're a little guy with bright blue hair, does that have anything to do with the game? Not really, well unless that means that you've lost your soul. Four of them to be exact, and it's your job to collect them. With each soul you collect, you will unlock a power that can bring you further in the game.
Souls in Stone is an atmospheric exploration/metroidvania game that will take you on a little journey filled with hazards. Well, basically one hazard each time you enter a different area. The power you've unlocked the last time will be the solution to get to the next door. Even tho there is one puzzle that can be quite hard to solve, the rest of the game is pretty easy to tackle.
