I think I got it working, I managed to log and "play" on the server.

You were really close to have a working service for minetest though. You 
were only missing the environment variable MINETEST_SUBGAME_PATH and 
*maybe* your profile-service-type extension was wrong (I just blandly 
copied how it was done for SDDM). I have attached your games.scm with 
the added fixes.
