The day loop — exploring and furnishing
Step
In short
Use every minute of daytime to stock your apartment with furniture, because what you place directly determines how far you can progress.
Each day cycle gives you free time to explore the supermarket and buy furniture to bring back to your apartment. The number and quality of items you place there build your Coziness score, which you need to unlock upgrades.
- Head to the supermarket search the area carefully because furniture is spread throughout.
- Return to the apartment place everything you bought before night falls.
- Check your Coziness score confirm it went up so you know the placement counted.
02
Surviving the night
WarnIn short
The single rule of nighttime is simple: stay inside until morning.
When the sun goes down, strange entities start moving outside the apartment. Your only job is to remain indoors until the night cycle ends.
Worth watching out for
Do not step outside for any reason once night begins.
Stay inside the apartment and wait for morning to arrive.
If you are playing with friends, make sure everyone is inside before night starts.

Coziness and apartment upgrades
Summary
In short
Coziness is the engine behind all progress, and furniture placement is how you earn it.
Coziness is a rating built from the furniture you have placed in your apartment. Once it reaches the threshold for an upgrade, you can improve the apartment itself. Upgrades can open up new furniture options, so the cycle of furnish, earn, and upgrade keeps driving the game forward across many sessions.
- Coziness earned by placing furniture; quality and quantity both matter.
- Upgrades unlocked by reaching a Coziness threshold.
- New furniture can become available after upgrades.
05
Co-op play with friends
Tips
In short
The game supports co-op, and having friends along helps in both phases.
The game is built to support co-op. During the day you can cover more of the supermarket by splitting up. At night everyone stays inside together.
Tips worth knowing
- Make sure every player is back inside the apartment before night begins.
- Solo play works, but expect to cover the supermarket alone and have no backup at night.

Common questions
FAQDo I need to spend Robux to progress?
No. Coziness is earned by placing furniture, not by spending real money, so the upgrade path is fully open to free players.
What should I actually do during the night?
Stay inside and wait for morning — that is the entire night objective.
Can I play alone, or do I need friends?
Solo play is supported. Either way the core loop — furnish by day, survive by night — stays the same.
Does the game change as I progress, or is every run identical?
The basic structure of day and night repeats each session, but unlocking upgrades changes what furniture is available to you and improves your apartment over time.
