Sleep Tight is an arcade shooter that supports joystick and controller controls. The gameplay includes elements of building structures and fortifications, as well as the nostalgic atmosphere of old-school projects of this genre. In the walkthrough, the player will have to create his own protected fortress from pillows throughout the day. At night, the base will be attacked by dark monsters trying to break through the castle’s defenses.

4 game modes in Sleep Tight:

• Operation Commando – is played from a first-person perspective, where the controlled character is constantly attacked by numerous waves of opponents.
• Teddy's Journey – creates an unusual monster trying to get to Teddy, rather than the central character. You will need to save the toy by any means necessary.
• Horror – takes the user into a dark room where you need to fight monsters from a third-person view.
• Pillow Fortress – invites gamers to collect materials during the day and build fortifications, and at night shoot with opponents.

Before the start of the session, the user can choose 1 of 12 characters with a unique appearance, weapons and additional abilities. Depending on the mode, the tasks change dramatically, as do some mechanics. Players use non-standard types of weapons, and for killing opponents they receive experience and useful items. Sometimes there are bosses or stronger waves of enemies.
