Hi t2k,
This PnP version was released in April 2020 during the "Stay at Home" campaign. Hans im Glück published downloadable rules in German and in English, the latter provided by ZMG as you can see in the link you provided.
The 48 tiles have the same size (3.5 x 3.5 mm) and distribution as Carcassonne Für 2. So you can try this one with the Demos-Print-and-Play rules.
If you want to get small meeples for this version, you can find 12mm meeples (the regular ones are 16mm meeples) in 12 colors on spielematerial.de:
