Dungeons & Badges

Check out the dungeon! (No, seriously.) See if you can solve the riddles and escape the dungeon that student Colin F. created in Teen.Code!
Colin made this Sphinx-like masterpiece in C# for the Teen.Code badge of the same name, inspired by the popular escape rooms. To achieve this badge, a student must code a game in C# (done and done!) that consists of a room or location, has clues hidden in secret places that the player must be able to hunt for, and, last but not least (and added because we know how our Gen-Z masterminds think!), must be both playable and escapable.
(Yes, I know, kiddos, it’s funny when you’re on the end that isn’t playing an impossible game. Trolls, all of you! Hmph.)
Go ahead and play! I promise there’s a way to win. (Right, Colin?)
