Thanks for playing! Yeah some things you might need to figure out over multiple playthroughs, and there's 6 endings in this demo so you have plenty to explore too. The full game is coming to Vermilion Arcade - Horror Collection on Steam, you can wishlist it now, it's a long way to go in developing this collection, so all wishlists are both appreciated as support as well as it's so you don't miss it when it comes out, which will take some time. Thank you!
