Cat Mail Co.

In-game tests and developer tools for CatLib and its mods. For mod developers, players do not need it.

Your own stamps for parcels: put PNG or JPG images into a folder and they join the game's decorative and weight stamps. Build a Thunderstore package of your pack in one click.

Join a game that is already running. Up to 8 players. Only the host needs it.

Foundation library for Cat Mail Co. mods.

The crash window of CatLib: a small Windows program that waits for the game to close and, if it crashed or froze, shows what happened and keeps a report. Comes with CatLib.

Stand a parcel across two or more parcels whose tops are level, like on the boat deck. Take one from under it and it slides off and falls.

A small board in the corner that counts the parcels of the level by destination: all of them, fragile, heavy, frozen and every other mark.

Set how much cardboard the repair table holds and how much a new day brings back, or make it unlimited.

Up to three extra labels next to every shelf label

Changes the crates and baskets on the boat deck and the stack height limits.
