It was free for a limited time, simply. Like Steam : now, it's become paid, because was free for limited time, too. https://store.steampowered.com/app/435120/Rusty_Lake_Hotel/

OH. Thanks a lot for this information on Steam. 

Indeed, the same game is free on steam.

It is a lifetime "promotion".

From May 1st (tomorrow, as I write this text), it will become a paid game.

So thanks again, I was able to acquire it. Without your information, I would not have guessed that.

Hi. No no ;) It's free. An App ? It depends.

For Rusty Lake, It was free (or payable by donation if we wanted)

But.... Now it's paid for again... Sorry. :/

Nevertheless, I was able to acquire it (windows 10) : it is a game in a compressed folder (.zip).

Opera GX simply shows us the games that have gone free.
