Pretty interesting submition, heres some subjections on stuff to improve.
when you jump, you lose control on your ability to move, and it makes it hard to move around.
The memories and the gameplay don't really follow a theme, the memories talk about war, but the character itself looks like a miner or an explorer, and it made the parts of the game fell disconnected.
overall: pretty interesting interpretation of the theme, and the idea of moving in the dark and throwing your torch is cool, good job.
