First off, thank you so much for your interest in Stir Fry Eighteen!
I'm fairly sure we can unlock some other modes in the near future.
I need to speak to the admins about which options they want for free users and if any need to be put on the premium side.
We also have a "tofu promo" card that we'd love to add to BGA.
I'll be in touch soon and will of course have to see if DrKarotte has time to make the updates to the client and test them.
We've been incredibly busy lately with 5-6 games planned for the next year and a half so I apologize for the delayed response.
We will let you know as soon as we have a timeline in place and thanks again GDC!
