He should've said that when he went into the house it would drop him down into an obstacle course and the stone will be tnt but the texture pack will make it look like normal stone so that he CANT escape.
Ok ik im SUPER SUPER late to this, but i feel like it should be said. Instead of making glass invisible, you should have made obsidian invisible and then stasis chamber. that way, he wouldn't be able to leave in time and it wouldn't explode.
