Shop fix in 4.92.10
The Shop could stay hidden after you closed it with Esc. You could press B or click the Shop button, but nothing would appear. Version 4.92.10 fixes that path. The Shop also clears a leftover hidden state when you open it again. We checked repeated purchases and reopening with the Back button, B and Esc, including after saving and restarting. Your existing saves are kept. If you still run into a problem, please tell us your game version, language and what you pressed just before it happened in Steam Discussions. That helps us reproduce it.

Material names in those explanations now follow your selected language. See the game in action The store now has a new gameplay trailer lasting just over one minute and six gameplay screenshots, showing reactions, planet formation, terraforming, construction, turret defense, and the skill tree. Later scenes were recorded in prepared test checkpoints to show those systems; they are not a timed start-to-finish run. Getting started Keep matter inside th...
