A 2D game where the player can switch between day and night time to solve easy puzzles in order to get to the end. The environment will slightly change when switching between night and day, making the night more threathening. The game is time based, which means the player must get to the end of the map before the time runs out in order to complete the game. The game is based on the sound of a beating heart, where the beating is the time indicator of the player.
