v15.12 A couple fixes, a couple features — Heartspell: Horizon Academy Steam update #937796

There's now a button to hide the UI on reward illustrations so you can see the art without obstructions. Cleaning up the credits a little. Caught a few text-voice mismatches. I think we've fixed a bug that in very rare circumstances would cause the game to not initialize properly, resulting in a weird-looking screen where you'd see very early concept art of Cassie.
