Bug fixes:
- Fixed an issue that would deteriorate the game's performance on some machines. Also, game's overall performance has been significantly improved;
- Fixed a bug that caused different save files to become locked after completing a game in one of the other saves;
- The description of "Ore Dust Extraction Module" is now displayed correctly;
- Issues with getting stuck in a tile, falling through a tile, or not being able to move between two tiles have been resolved (I am using "should be" here because I could not reproduce them after fixing the issue. If they are still present, please let me know);
- Issues with earthquakes not stopping after returning to the surface or killing a player above ground have also been fixed (again, I could not replicate these bugs after making the changes, so if they still occur, please notify me);
- A bug where one of two metal spikes would not disappear after destroying the tile they were connected to has been resolved;
- Problem with tiles appearing incorrectly on level 3 has been resolved.
Other changes:
- The settings screen will now close after pressing "Save settings" or "Cancel". Yes, this was a very requested (and easy to implement) feature :)
- Added descriptions to the S-tier upgrades briefly and intentionally vaguely explaining their special abilities.
