Congrats on the release! I liked the first episode, good thing you completed the game.
Putting on moderator hat: Please create a new database entry for the full game. Otherwise, the download stats, nominations, links from extern etc. would be messed up. Additionally, if you add a new entry, you will be able to participate in the AGS awards 2018 with the game.
To make it clear that the full game was released, you can edit the page of chapter 1 and add a note and link to the full game. I have no idea why you cannot update the entry yourself, it looks alright to me. However, I can update it for you, if you want.
