A first-person horror game. The player will play a character who enters the dreamland. Gather the necessary props to escape in the dreamland, and be careful of monsters during the chase. If you really can't escape, you can try to enter a deeper dreamland (but you may not be alone there)
As the level deepens, monsters will have different characteristics. The previously seemingly safe hiding spots will become less safe and the difficulty will continue to rise.
The sound of the bell not only reminds the time, but also reminds the monsters to change. Maybe the hiding spots that were commonly used before should be changed.
