...and he's not too happy about what you did. this guy's name is Swindler, and he's a non-canon anti-cheat character from the Wavelength Realm. if you somehow "cheat" in it, you'll get teleported to his "serious room" (stanley parable reference lol), and he'll go on and on about how you should be doing things legitimately around these parts. oh, and you can't leave until he's done. if you somehow "cheat" 2 more times, then he'll just trap you in his "serious room" for god knows how long. aaaand that's when you're "banned" from the Wavelength Realm. btw did i forget to mention he's one of Impediment's creations?
