Congratulations and good luck there. But it was just a suggestion from my end that, you could unlock all the chapters of limited cards step by step and not in one go, like for eg, about 3 to 4 months of the intro of the card, you could unlock some more chaps or you could just release it step by step in later updates where the supporters would enjoy a whole lot more than the public. Again, just a suggestion from my end, but you know, I have seen a lot of other devs implement this and it has worked for them I guess. You could try this after your business model settles down and you finally have enough funds. Depends on you ultimately, and again congrats.
