So you've purchased a key for one (or more!) of our games and aren't quite sure how to activate it? No sweat, you've come to the right place.

Key Type

The first step is to find out what kind of key you have, we currently distribute two types of key:

Steam Key

You can identify a Steam key as 3 groups of 5 characters separated by dashes, like this:
It will probably also say "Steam" near it somewhere. If your key looks like this, jump ahead to Activating A Steam Key.

Itch Key

You can identify an Itch key as starting with "" followed by about 12 more characters, like this:
If your key looks like this you can jump ahead to Activating An Itch Key.

Your purchase may have also come with one of each, in which case you can choose to activate either one, or both.

If your purchase came with an Itch key but not a Steam key, there may also be a Steam key attached to the Itch one. See Getting Steam Key From Itch below.
