Yes, actually! I just sent out a promo code email for previous purchasers. It's the first time that I've ever tried to do anything like this, so I hope it reached everyone with the appropriate links all working correctly... I sent it to the email address that Itch has on file for purchases. Essentially it's a $5 coupon for the game, and if people don't want it or don't need it, they can always gift the link to a friend or post it up on a community board. Doesn't bother me at all.
