While playing the game, rooms can be tricky: you don't know what they can do until you build and fully upgrade them, and when you upgrade to a new ship, you have to build them all over again, during which you'll often run out of materials, causing it to take forever before you're back to where you were before you upgraded. This guide is here to help you with that.

Rooms come in different types, but they all have things in common:

• With the exception of the Bridge and Ladder, rooms will cost materials to build (the exact materials differ per room type), and you'll get some of the materials used to build back when you choose to dismantle the room (typically the most complicated ones). Materials expended on upgrades are not refunded.
  
• HP: rooms start with 30 HP, and if they take too much damage from monsters, they'll be destroyed, which will refund you as if you'd dismantled them. With the Armor Up upgrade (cost: Field Generator x1, 15 Stamina, 20 seconds), you can increase the room's max HP to 50; doing so also unlocks the Major Armor Up upgrade (cost: Field Generator x2, 15 Stamina, 20 seconds), which will increase the max HP to 100. The only possible exception is the Arcade (when you try to select it, you'll enter Arcade mode, so I was unable to determine its HP).
  
• Assignment slots: most rooms allow you to assign only a single mouse to them. Through the Assignment Enhancer, Assignment Enhancer II, and Assignment Enhancer III upgrades (each has the same cost: Chair x1, 15 Stamina, 10 seconds), you can increase this to 2, 3, and 4 assignment slots. Although most tasks will require a single mouse, assigning multiple mice to a room ensures that if one is resting, eating, or being healed, another can still perform tasks.
  Other rooms have a fixed number of assignment slots, which cannot be increased.

Notes:

• Group A recipes are available once you build the room. Other groups require you to upgrade the room first.
  
• Unless specified otherwise, recipes require 1 mouse, 15 Stamina, and 40 seconds; upgrades require 1 mouse, 15 Stamina, and 20 Seconds.

From top to bottom, the list of rooms is as follows:

Purpose: allows mice to recover Stamina by automatically resting in them.
