Hello. You have just won a giveaway for "Tumblestone"
https://www.steamgifts.com/giveaway/zJzYM/tumblestone/winners

However, I would like to make sure you receive the full version of the game as you should, not the free trial version of the game which some people are giving away.

It will still be called "Tumblestone" in your Steam library, but if you have the trial, when you start the game it will say on the title screen "Trial" right under the Tumblestone logo.

You can also check your Steam licenses (https://store.steampowered.com/account/licenses/) and it will also clearly say "Tumblestone Trial".

If you have a moment, please can you check? I would like to make sure you received the full game as intended.
If you have a trial version, you can only play online with friends who invite you, and only as the "grey blob" character. Additionally, the story mode is limited to just 30 sample puzzles, compared to 360 puzzles in the full game.

People with the full version used to have the ability to create trial keys freely, which is why so many trial version keys appeared.

Please let me know. Thank you.
