+
+[Dwarf World] by [Alex Ene][@_AlexEne_] has added a couple of updates and
+improvements:  
+- Dynamic ligths and light propagation so deeper caves are darker.
+- An in-game feedback button that people can use to report bugs or
+just give general feedback.
+- All random numbers are from seeded generators so it makes bugs easier
+to reproduce.
+- A big chunk of a replay system is finished.
+This should help a lot with reproducing issues. Plus, it's really fun to watch.
+- Bug fixes and performance improvements, mostly related to
+rendering and culling systems.
+
+If you're interested in keeping a closer eye on the project and monitor
+it's progress,
+you can join the game's [discord channel][dwarf-world-discord].
+That's where the pre-alpha builds will drop there once they are
+ready to be seen by a wider audience.
