A little known feature of Steam is that it offers RSS feeds for any app/game/whatever shared using it.

The URL is also very simple to use:

https://store.steampowered.com/feeds/news/app/$AppIDCode language: JavaScript (javascript)

You can then replace $AppID by the application ID of your game.

For instance, if we want to monitor Resonite, app ID 2519830, you will need the following URL:

https://store.steampowered.com/feeds/news/app/2519830Code language: JavaScript (javascript)

There, super easy!
