I've used LibGDX a few years ago. It was easy to create a basic game, but it seems to be moribund today. Most of the showcase projects are 4-5 years old.
LibGDX is still alive and well, and just released a new version recently. The API is relatively "finished" which imo is very nice and means old tutorials still work, and there's some exiting things maybe happening with getting the kotlin version to work on web without GWT (which is java only)
Cool! Thanks for following up. I wonder if there is a room for LibGDX going forward now that Godot is getting big. I expect to see some consolidation among open source engines, with Godot becoming the big all-purpose engine and things like Love and Ren'py for more niche use cases.
