I have added two bundle options, allowing to pledge for multiple copies of the game. If you would like to pledge for more than two, please contact me directly. All backers who pledge for either bundle pack are eligible to choose between white or grey when the campaign ends. The choice will be available on the backer survey.
Why not both? When backing at the $249 level, your name will be included in the game credits listed at the title in all versions, along with a message of your choice that will only be included on your personal cartridge. If you'd prefer to keep your name out of the credits, that's fine too. It's all up to you!
