One tweak
Please figure a way to limit the amount of times the "Checkpoint Saved" screen comes up. I would suggest a if or a loop that would make it so that the thing only comes up once, and it could even re-save once you die, but standing still on it, and having the screen flash white REALLY disrupts a game about playing in the dark.
Otherwise the game is fun, the idea is amazing, and it was fun enough to warrant a second play through.
Congrats
