Can you keep your Loop Dungeon demo save?

Yes, if your demo was version 0.9.0 or later: the full game detects the save on first launch and offers to transfer all progress. Saves from demos older than 0.9.0 cannot transfer; instead the game offers a one-time resource compensation based on your old progress, or a clean start.

It happens once

Both prompts appear only once. After a transfer, playing the demo again does not affect the full-game save. If you skip compensation, you cannot claim it later.

Why old saves break

The developer says the game went through major changes during development, so pre-0.9.0 saves are not compatible. The title screen screenshot shows version 0.9.0.

Demo numbers

In September 2026 the developer reported that more than 8,500 players had tried the demo, with a median playtime of 1 hour 25 minutes, and over 5,500 wishlists.
