We just released UpvoidMiner 0.4.70!
We are still not done with the major changes in the engine core, so there are still many bugs and crashes left in the game. However, we implemented some gameplay features to UpvoidMiner. The terrain contains flat valleys and a desert biome now, and you can chop trees with your axe. You will have to delete your savegames folder in Engine/Savegames after updating.
You might have noticed that we stopped issuing our weekly updates. From now on, we will publish progress updates when we have new features to show or when a new version is released.
