hi hennersbbq thanks for the kind words && for holding us accountable lol!!! you can read more about why we're taking ages (grovelling for forgiveness) in our blog but essentially development has been slow due 2 us working on other projects!!!! sorryy
to answer your questions the GBC ROM will definitely come with the itch.io purchase, and most likely be packaged along with the .exe for the Steam purchase too.
in terms of release date, we dont want to jinx anything but will definitely post abt it when its close! hopefully SOON™ <3<3
