Can Em All how to transfer demo save to full game is a manual file copy, and the developer recommends against doing it: demo progress does not carry over by design. The copy works on Windows and takes five steps, but the transferred file does not match the full game's upgrade set, so treat it as an experiment rather than a transfer.

Can Em All how to transfer demo save to full game: the honest answer

The honest answer is that you should start fresh. The developer confirmed it twice, and the reason is about the game's design rather than a technical limit:

  • The full game changes the skill tree and adds new upgrades.
  • It adds lore emails, the slot machine, rebirth and more.
  • Carrying even your demo money across could break the progression balance.

So the copy below is a way to look at your demo progress inside the full game, not a supported transfer.

Why demo progress does not carry over

  1. The demo's upgrade list is not the full game's upgrade list.
  2. The full release adds systems that did not exist in the demo — lore emails, the slot machine, rebirth.
  3. Demo money carried across could hand you a balance the full game's progression was never tuned for.

The supported way to start over is the factory reset, which is a real mechanic with its own reward: permanent upgrade tokens that carry between runs. That is what the prestige guide covers.

How to move the demo save by hand

This is the procedure that works on Windows:

  1. Press Win+R, paste %USERPROFILE%\AppData\LocalLow\LuisDev, and press Enter.
  2. You should see two folders: Can 'Em All Demo and Can 'Em All.
  3. Open both of them and find save.sav in each.
  4. Copy save.sav from the Can 'Em All Demo folder into the Can 'Em All folder, overwriting the file that is already there.
  5. Launch the full game.

Before you overwrite anything, copy the full game's own save.sav somewhere safe. The exact paths are in the save location guide, and the cheats and mods guide covers the other reason players start moving save files around.

What a transferred save gets wrong

The file loads, but it was written against the demo's upgrade list, and the full game has a different set.

  1. Upgrade nodes you already bought may not exist in the full game, and their money is spent on nothing.
  2. Nodes that do exist may unlock out of order, because the tree itself changed.
  3. Progress counters that feed the feeding achievements may sit at values the full game's balance never produces.

If the game refuses to load the file, put your own save.sav back and start fresh. Nothing is lost that was not already lost when you overwrote it — which is why the backup in step 4 above matters. The exact path of that file on disk is in the save location guide.
