Walking at night you find some attractive ruins. Should you explore them? The ruins will start to trap you, prompting you to light colored circles in order to move forward and jump into another set of ruins. The puzzles become more complex as you figure them out, showcasing new mysterious ruins that have been waiting for a human to take on their challenge. WASD or arrow keys to move. Space or R to restart a level.
