Challenges

 * Electrician
 * Electricians have repaired at least 10 electrical objects. The experience gained means they will never be electrocuted by an electrical object again.


 * Plumber
 * Plumbers have repaired at least 10 plumbing objects. They are so good at repairs that plumbing objects repaired by them never break again.


 * Tinkerer
 * Tinkerers have finished at least 10 unique upgrades on household items. Installing the "Unbreakable" upgrade on multiple objects only counts as one unique upgrade, so it helps to experiment with different upgrade options! Tinkerers never fail when upgrading objects.

Glitches
The player can give both Unbreakable and Perfect upgrades to the same Teleporter by taking advantage of a glitch by completing the Perfect Teleportation upgrade first, then starting a new upgrade for Unbreakable, and canceling it after only some work is done.
