Very Positive reviews on Steam

The redemption deadline displayed in your Humble profile is a lie. The keys do not expire. They just remove it from your Humble account.
You only need to reveal and save your key somewhere before 5am AEDT February 1 and you can then redeem it at any time in the future

Includes: Deponia, Chaos on Deponia and Goodbye Deponia.

Does NOT include Deponia Doomsday.
