The latest patch adds requested features and fixes more of the reported bugs. Added features:

• Mouse can be inverted (Settings -> Controls -> Mouse)
• Keys to all actions can be re-mapped
• Global volume controls (Settings -> Gameplay)

Fixes:

• Collisions should appear correctly now
• Wirecutter should not crawl on the floor after load anymore
• Wirecutter minigame should now work correctly

Experimental (I was not able to reproduce, but made a few changes):

• Keys should no longer disappear after opening the garage door
• The scaffolding should work fine now

Note: The diagonal rod resting against the scaffolding is really NOT to be climbed. It is not a bug if you fall down from it.
