Thanks for the quick reply.
I see. I have previously bought "Among Us" on itch io and it came with both an itch io download link and a Steam key as well. Isn't something like that possible for you to do with your game too? if you can't change the price on this page, then maybe make this page "Chapter 1" and then make a new itch io store page titled "Chapter 2 onwards" or something like that (like you have with "LIRE Prototype") that has the Steam price? I prefer DRM-free itch io rather than Steam to be honest.
I already have V1.08 downloaded, but now that you mention it, I just checked and the download link is gone (it says "Nothing is available for download yet."). This could prove to be an issue for future customers and myself if something happens to my PC, so could you please fix it? I don't know how many have bought the game, but I believe it would be annoying to receive lots of mails from customers who suddenly notice their download link is gone lol.
