This is a great start! The riddle aspect is really cool, and I like the idea! For void tiles that you don’t intend the player to walk on, it might be best to use the Inquisitor tileset. The REFMAP void tiles are a dark navy blue that stands out, while Inquisitor void tiles are actually black. Also, you have a programming bug in your first invisible actor. Great work! You’ve really improved your storytelling skills, and I can’t wait to see where this goes!
