What This Mod Unlocks

• All 50 levels are unlocked from the start.
• All in-app purchases are free, including any additional invention packs.
• Interstitial and banner advertisements are completely disabled.
• The "Mackles" collection and related workshop exploration features are fully accessible.
• The difficulty adjustment setting (fake objects toggle) remains functional but is no longer gated.

The mod is activated upon launching the app. No initial tap or menu is required; the unlocked content is immediately available in the level selection screen. The ad removal is passive and requires no user interaction.

Pettson's Inventions Mod 4 requires Android 6.0 or higher. The installation requires approximately 320 MB of free storage. Root access is not required.

Installation follows standard sideloading procedure. First, enable installation from unknown sources in Android settings. Second, download the mod APK file. Third, locate the downloaded file using a file manager. Fourth, tap the file to begin installation. Fifth, launch the game from the home screen.

Several edge cases exist. The mod functions entirely offline, so there is no server detection risk. However, progress is stored locally. Clearing the app's data will reset level completion status, though levels remain unlocked. On some devices with custom ROMs, the ad-blocking may cause a brief loading stall instead of a clean skip. The mod is confirmed for version 1.1.0; future official updates may break functionality until the mod is updated.
