A LOCAL co-op is planned for. There is a mistake in the $75 reward which mentions another key is needed for co-op; this is not true! The key for $75 is simply to give to a friend.
The key for the full game will be distributed digitally once the game is complete. The key for the closed beta will also be distributed digitally, at the latest at the end of the 30 day kickstarter.
While we're planning on both releasing a Mac and Linux version, this all depends on the functionality of GM Studio and whether or not it has any compatibility issues with our current project. Crossed fingers!
The rewards with * does not come with another item to create.
The rewards with ** comes with ONE item to create, of whatever tier of your choice.
