Digital Circus Horror is a great first-person horror game that will show you everything you need to know about the night circus.
After a set of tests, you'll have to do what Kane tells you to do. But watch out—the scary Pomni and Jax are already on the lookout and will be waiting for you at every turn. The park's lights go out when you talk to Kane. To get the power back on, you need to find ten stars and connect five electric panels. Now that the hero has done this, he or she will be given a new job. You need to go on three rides and get the given number of stars.
Keep your eyes open while you do the task because creepy circus artists are sneaking around. They are ready to attack at any time and won't let their prey go. Run away right away if you hear scary sounds and see eyes that are glowing red. After the chaos dies down, you can continue your search.
Have fun and good luck!
