I'm sorry, I'm not familiar with the method that my publisher is using for distribution. If you have any problems with downloading the game you can reach out to Incube8 and they will fix it for you. This game is pretty old-school in the sense that since it's being published on a cartridge it was extensively tested before release. It's unlikely that we will have updates unless there is a major bug that was somehow missed.
Thank you for your reply Ben. That's a relief to hear, thank you. I'll ask the publisher then. By the way: I'm very much enjoying the game on my good old GBC (thanks to EZ Flash)! The atmosphere is impressive, the story original and the production values top notch. You've created a very unique game here!
