I love the idea! It's clear how it will work, and it's a fresh take on this theme I've never seen before.I wish there was some way to see what you were getting into before teleporting, but you did a good job making the solutions obvious. I also love the use of postprocessing to make 2005 look retro, giving you a clear and self explanatory way to see which time you were in. One little problem I have is that 2005 sounds way quieter then 2030, so it really scares you when you switch back.
