The heartstuck page has the text and the background as the same color, so you can't see anything unless you ctrl+a to highlight it. Is that intentional?
Also it doesn't seem to have a download link either, just a big gif of a pixel heart.
Yes, the game is being developed as we speak. I am just being a bit spooky with the page right now. You know how wacky those earthbound inspired RPG's can get!
You can't read any of the text without highlighting it first. The links if clicked lead to pages with the same issue. It looks blank until/unless you highlight the text first.
