About KOTAMON: My Sis Found A Super-Rare Card In Her Cereal Box, So I Became A Garbage Man To Find The Entire Collection And Earn $1,000,000

KOTAMON is an indie simulation where you wander a dump site with a trash bag, looking for hand‑drawn collectible cards and odd treasures. The game imposes no time limits, letting you explore at a relaxed pace.

You can mend damaged cards, swap duplicates, and upgrade your abilities using the money paid by the site owner. Earnings help you chase the goal of a $1,000,000 collection.

01 / THE GUIDE

Exploration and Collection

The dump site belongs to you; you may sift through piles or simply run around with a trash bag. Every corner can hide a card or a misplaced object that adds to your haul.

Finding items is the core loop. Each find can be examined, kept, or handed to the site owner for payment, and the game tracks progress with Steam achievements and stats.

  • Check low‑lying piles first; many cards rest beneath debris.
  • Carry multiple items before returning to the owner to reduce trips.

02 / THE GUIDE

Card Collection System

Dozens of unique cards feature hand‑drawn illustrations by noted artists. Collecting sets of different colors triggers rewards, and an unopened cereal box may contain a super‑rare foil card.

Cards can arrive crumpled, torn, or damaged, but you may mend them or swap them for better versions. Improved condition directly raises a card’s market value.

  • Mend a card before selling if the repair cost is lower than the price increase.
  • Swap duplicate cards to fill missing colors more quickly.

03 / THE GUIDE

Upgrading Your Character

You can purchase upgrades that make you better, faster, stronger, and more efficient at clearing garbage. Each upgrade turns you into a trash‑mowing machine, increasing the amount you can collect per run.

Upgrades are bought with earnings from the site owner, allowing gradual improvement of speed, bag capacity, and mend efficiency.

  • Invest early in speed upgrades to boost overall earnings.
  • Balance bag capacity with mend tools to avoid over‑loading on damaged cards.

04 / THE GUIDE

Earnings and Rewards

The dump site owner compensates you for each find, providing a steady income stream. High‑value cards and rare foil cards generate especially large payouts.

Your earnings can be spent on upgrades, card mending, or simply saved toward the ultimate $1,000,000 collection goal.

  • Prioritize high‑value items early to maximize cash flow.
  • Reserve a portion of earnings for unexpected rare card discoveries.

05 / THE GUIDE

Platform and Controller Support

KOTAMON runs on Windows and offers full controller input, including DualShock and DualSense support via the Steam Input API. The game lists full controller support among its features.

Steam features such as Cloud saves, Trading Cards, and Family Sharing are available, ensuring your progress travels with you across PCs.

  • Enable Steam Input to create a controller layout that matches your preferred actions.
  • Activate Steam Cloud so your collection syncs between machines.
