Combat cards solve the fight in front of you; Explore cards shape what you can do between fights. Foresight gives each character another defining layer. Judge every choice by whether it keeps you alive now, improves the run permanently, or prepares the next fight—and be suspicious of picks that do none of the three without another missing piece.
Learn the split before learning a build.
Shroom and Gloom describes itself as a first-person roguelike double-deckbuilder. Its defining idea is not simply “a large deck”: the game separates actions into a Combat deck and an Explore deck, then asks you to make both halves support the same run.
Used in fights for attacks, skills, defense, targeting, and survival. A Combat pick should answer a fight problem or reinforce a combat plan you can already support.
Used for movement, searching, environmental interactions, modifying cards, and unlocking weapons or abilities between fights.
In combat, solve the current failure first.
The official description confirms the Combat deck's role, but it does not publish a complete current rules reference for draw counts, energy, or turn structure. Begin with observable needs rather than a memorized formula:
- Name the immediate danger. Decide whether the fight is testing damage, defense, targeting, or recovery.
- Prefer cards that function now. A payoff that needs a resource or enabler you do not have is a promise, not present value.
- Count dependencies. Each extra setup card makes it more important that the rest of the chain is already reliable.
This is an editorial way to review a choice, not a claim about a hidden scoring system or a universal best strategy.
Exploration is where the next fight starts.
The Explore deck handles movement and interaction outside combat. Official material also ties exploration to modifying cards and unlocking weapons or abilities. That makes an Explore choice part navigation, part resource planning, and part long-term deck development.
Cooking is one visible bridge between those layers: enemies can be seasoned, skewered, roasted, and eaten to restore health, or used for soup. Treat that as a recovery and build-planning system, but do not assume an exact recipe, healing value, or required sequence unless the current build shows it.
Does this interaction address health or another pressure that could end the run soon?
Does it improve or modify something that will keep paying off later?
Does it create access, recovery, or a tool the next encounter is likely to need?
Foresight is part of character identity.
The Early Access launch announcement names five launch characters: Paperboy, Janitor, Lunchlady, Activist, and Concerned Parent. Each has a distinct Combat starting deck, Explore starting deck, and a base Foresight card described as changing how that character plays.
For a beginner, the safe takeaway is structural: a character is more than a portrait or a single deck. Read the two starting decks and Foresight together before deciding what the run appears to reward.
Paths change the pool of decisions.
At the September 10 Early Access launch, the official count is two playable pathways, each with its own characters and roughly 300 Explore and Combat cards. “Roughly 300 per pathway” is a content-scale description; it should not be read as proof of 600 completely unique or simultaneously obtainable cards.
The launch announcement says quests unlock advanced characters and The Facility. It also says the game autosaves after each combat victory and when leaving a dungeon. That tells you when progress is recorded, but it does not fully document what persists after failure or how every unlock condition works.
Use one loop for every offer.
| Question | What it tests | Warning sign |
|---|---|---|
| What does this do now? | Immediate survival or utility | The card only matters after several more specific picks. |
| What does it improve for later? | Permanent growth or repeatable value | The benefit duplicates a job the deck already handles well. |
| What does the next fight need? | Preparation and resilience | The plan only works when cards arrive in one ideal order. |
| What am I giving up? | Deck quality and opportunity cost | The pick adds another dependency without fixing a weakness. |
A current Janitor/Facility run shows why this framing helps: choices around Data, Machines, Gunk, healing, and deck thinning repeatedly force tradeoffs between present strength and a future payoff. That video is one run, not a prescribed route.
What this beginner guide does not claim.
- A default character, default pathway, or exact first-run walkthrough.
- Exact draw, energy, rest, healing, or danger-growth values.
- The complete contents of any character's starting decks.
- Exact quest requirements or everything retained after a failed run.
- A universal best card, build, route, or cooking sequence.
- That records found in an unofficial database are obtainable in normal play.
Older Prototype and Steam Demo guides may still be useful for forming questions, but their deck lists, values, and progression rules are not treated as current Early Access facts here.
