Quick answer
v1.0.5 adds Panel Rack, Clear Items, a quit confirmation with Save and Quit, a flat-placement rotation shortcut, broader input rebinding, tool and spawn fixes, key-item recovery, and more flexible physical-button controls.
Official changes and practical impact
| Official change | What it changes for players |
|---|---|
| Panel Rack upgrade with multiple levels | Carry more than one panel; building and rebuilding large lines requires fewer trips. |
| Clear Items button in pause menu | Recover from dangerous loose-product counts. Cleared items do not refund money. |
| Quit confirmation and Save and Quit | Exiting is less ambiguous and can preserve progress through an explicit option. |
| Double-tap reset rotation to place flat | Reduces friction when aligning panels horizontally. |
| Expanded action rebinding, including scroll directions | Players can fix conflicts that previously appeared invisible or impossible to change. |
| Torch and UV Lamp collection/activation fixes | They work when collected; T remains the default activation key. |
| Spawn-loop and blocked-tube fixes | Fewer cases of repeatedly falling or being trapped by tool piles. |
| Key-item and ore recovery | Stuck key items respawn; affected ores can be added directly to the bank. |
| Physical buttons respond to F, E, and LMB | More consistent interaction across nearby controls. |
Building changes
On v1.0.5, use Clear Items to reset a failed layout and double-tap reset rotation to place panels flat. The Panel Rack reduces trips while building, but it does not change a layout’s geometry.
Advice that changed
- Use Clear Items before dismantling a clogged layout.
- Choose Save and Quit when you need to preserve progress before exiting.
- Check the expanded rebinding menu if a tool input no longer matches an older guide.
- Treat key-item softlock advice written before Aug 22 as outdated.
- Ignore Phase 3 instructions that depend on the destructive event removed on Aug 20.
Hotfix note
The developer also reported a small follow-up hotfix for erratic Panel Rack behavior, missing ores, and pickaxe issues. Treat screenshots or bug reports from the first 1.0.5 hours cautiously.
