How to Play cat mail co: Tips, Controls & Strategy

1. Incoming — A boat (and the leftover mountain of backlog) feeds new parcels into your warehouse.
2. Handle — Pick each package up, read what it needs, weigh it if postage matters, apply destination labels, mark fragile/heavy when required, and stamp it in a way that feels right to you.
3. Store — Place parcels on shelves, in rooms, or in temperature-appropriate spots so you can find them again. Bad storage is the real “fail state,” not a countdown timer.
4. Outgoing — Load correctly sorted mail onto the boat so it leaves for the right destination (mis-sorts can come back damaged).
5. Counter work — When customers arrive, match their (often vague) request to a parcel in stock and hand it over.
6. Progress — Clearing backlog and shipping volume unlocks rooms, tools, destinations, and night-side package secrets that change how some mail should be treated.

There are no hard timers or punishment clocks in the design: the pressure is logistical. Organization is the difficulty curve.

1. Start the session and finish the tutorial prompts. The early hand-holding walks you through accepting parcels, stamping/labeling, boat loading, and customer hand-offs. Do not skip these interactions—later systems assume you know them.
2. Clear a small working path first. Move the nearest pile just enough that you can walk, reach shelves, and see the boat/counter without climbing over boxes. A path beats “perfect storage” in the first ten minutes.
3. Process one parcel fully before grabbing the next. Pick up → check destination/handling cues → stamp and label → put it either on an outbound boat stack or on a shelf you can name in your head (“left shelf = City A,” “floor pile = unknown”).
4. Load the boat deliberately. Only put outbound mail that is labeled for a destination you are currently shipping. If the game flags returns or damage when sorting is wrong, treat that as a verification step: wrong label = fix before load.
5. When a customer appears, stop sorting. Listen to what they say, scan your labeled areas first, then try candidates one at a time. If they reject a package, put the wrong one back in a “not theirs” bin instead of dropping it randomly.
6. Before you end the day-ish rhythm, reset the floor. Sweep loose parcels into temporary stacks by type (letters vs boxes, heavy vs fragile if those tags appear early). Pre-crastination—tidying before the next wave—is how the game stays cozy.
7. Explore unlocked space when the pile shrinks. Clearing backlog can open rooms and reveal photos/history of the post office. Note new storage zones and any special handling rules (heat, cold, fragile) before the volume climbs.

Public listings and player write-ups treat Cat Mail Co. as a keyboard + mouse, first-person game (controller support has been discussed as a post-launch addition, so do not assume a full gamepad map).

Expect something in this family—verify on the host’s pause/settings overlay rather than memorizing this list as official:

On a browser host page, click into the game canvas first so keys reach the game, then open any Controls / Settings button the portal or in-game menu shows. Rebinding is available in the PC version; if your build has it, bind stamp and interact to keys you can hit without looking away from shelves.

1. Label shelves the moment you invent a system. Destination, size, or “customer pickup” zones beat visual memory once you pass a few dozen parcels. Future you (and co-op partners) will use the labels more than the art.
2. Treat vague customer dialogue as a filter, not a riddle. Match the *constraints* they give (color, size, destination, “heavy,” “smells cold”) and keep rejected packages in a short-list pile so you do not re-test the same box forever.
3. Separate fragile and heavy early. When those tags appear, give them their own shelf height or room. Mixing them makes boat loading and night-side magic rules harder to read at a glance.
4. Respect temperature rooms once they unlock. Parcels that need hot or cold storage are not flavor text—parking them in the wrong climate is how “I thought I was organized” turns into a scavenger hunt.
5. Use night as inspection time. Moonlight can reveal properties you miss under daytime lighting. When the mood shifts, walk the shelves again before you assume every label is complete.
6. Ship volume, don’t hoard forever. Progress comes from sending mail and clearing backlog piles. Decorative stamp collections are fun, but undelivered mountains block rooms and story photos.
7. In co-op (up to four), assign roles, not vibes. One person stamps/labels, one shelves, one boat-loads, one works the counter. Shared chaos without roles multiplies mis-sorts.
8. When placement snaps refuse a shelf, step back and reorient. The snap system can reject a box that “looks” like it fits—rotate, lower it, or free a full row instead of force-stacking.

• Spreading parcels across the entire floor “for later.” Later never comes; customers will, and you will fail the hand-off.
• Grabbing five packages at once mentally while carrying one. Finish stamp → label → home before the next pickup.
• Ignoring boat direction while obsessing over stamps. Pretty stamps do not fix a wrong destination.
• Assuming cozy means zero systems. There is no timer, but wrong storage, wrong climate, and vague pickups still punish sloppy layouts.
• Throwing rejected customer packages back into the main pile. You just guaranteed a second wrong attempt.
• Skipping backlog clears because “new mail is more fun.” The mountain is both story and map unlocks—leave it and the warehouse stays a maze.

Is Cat Mail Co. free? A free demo has been available on Steam, while the full release is a paid PC title. Browser host listings can change—check the play page you open for whether you are in a free web build, demo, or a link out to the full game.

Do I need to download anything? On Steam, yes (demo or full install). On a browser host, you usually play in the page after the embed loads; still allow the tab to use keyboard/mouse focus.

Is it single-player? Yes. You can run the whole post office alone. It also supports online co-op for up to four if you want to split sorting, stamping, and counter work.

What genre is this, really? Cozy management / life-sim: first-person package handling, warehouse organization, light narrative via backlog and photos—not combat, not a high-score arcade.

Any beginner tip that matters most? Build a labeled system before volume spikes. The game stays relaxing only if your shelves answer “where is X?” faster than your memory does.

Is there a wrong way to stamp? Functional labels and handling marks matter for delivery; decorative stamps are largely personality. Follow the package’s needs first, then make it cute.
