Hi miners, 😄
Thank you very much for your continued support, reports, feedback, and suggestions.
Following the recent expansion of the late-game progression, this update focuses primarily on improving performance for larger and more developed saves.
We have optimized several systems that can become heavier as mining operations continue to grow, including how large amounts of stored items are handled and how employees search for certain tasks. We have also added three more Delivery Trains for later progression, improved keyboard input prompts, and added content monitors to additional conveyor machines.
Performance results may still vary depending on the device, save size, and factory layout. These improvements are part of our ongoing optimization work, and we will continue reviewing performance and making further improvements in upcoming updates.
Here is what is available in the latest version.
Main Updates
1. More Delivery Trains
Three additional Delivery Trains are now available as players continue progressing through the later Levels:
Delivery Train Cave 1B — available from Level 25
Delivery Train Cave 3B — available from Level 30
Delivery Train Cave 3C — available from Level 35
Each train can be purchased individually after reaching its required Level.
These additional trains provide more delivery options as mining operations expand across different Cave Areas and production volumes continue to increase.
Performance Improvements
1. Late-Game Performance & Save Optimization
We have made further optimizations for larger saves with more developed mining operations.
Starter Machines containing very large amounts of stored items now use a lighter save-data system. This can significantly reduce the amount of data that needs to be stored in certain large saves, helping reduce save size, memory usage, and loading workload.
We have also optimized how employees search for certain tasks.
This particularly affects activities such as:
Toxic Gas handling
Box merging
Employees can now search for these tasks more efficiently without repeatedly placing the same level of processing load on the game.
The overall impact of these improvements may vary depending on the size and complexity of each save, as well as the device being used.
We will continue working on further performance and optimization improvements in the upcoming updates.
Improvements
1. Keyboard Layout-Aware Input Prompts
Keyboard input prompts now better reflect the keyboard layout currently being used by the player.
For example, players using an AZERTY keyboard will now see movement prompts using ZQSD instead of the standard WASD layout.
The displayed prompts can also update when the active keyboard layout is changed while the game is running.
This improvement applies to keyboard input prompts throughout the game.
Please note that the in-game virtual keyboard will continue using the standard QWERTY layout.
2. Conveyor Lift Content Monitors
We added content monitors to:
Conveyor Belt Lift
Vertical Conveyor Router
Players can now use these monitors to check the items currently inside the machine, including the item types and quantities passing through it.
This provides additional visibility when checking item flow across vertical conveyor setups.
Thank you again for your continued support, reports, and feedback.
As mining operations become larger and more complex, we will continue reviewing both gameplay systems and performance to make larger facilities more comfortable to manage.
Performance optimization remains an ongoing process, and we will continue making improvements based on internal testing and player reports in the upcoming updates.
If you encounter any issues or unexpected behavior, please report them through the in-game report feature or through the Steam Discussions page so we can investigate further.
See you in the next update!
