Congratulations on finishing your prototype. I had to give up on my VN because I wasn't liking the ending and did not have enough sounds or visuals, so kudos for getting yours done :)
I have two suggestions. One, check the "full screen" option in the game page's settings. I have a small screen and had to zoom out to about 75% to see the whole game, making the text so small I could barely read it. (This can actually be done during voting since it's only game files that are locked.)
Two, look into optimizing it. For some reason, despite being a VN as opposed to a large detailed 3D world, the game put my GPU up to 100% on my slow-ish computer, so I ended up unable to play it :(. I don't know if it's caused by too many frames per second or some other aspect I don't know since I don't use Godot.
(Had to type this quickly, so I hope I'm not coming off blunt (‘-’*) )
