I love this concept and you executed it really well. I'm very curious about the way that the bidding is set up. I tried to test it to see if it was responding to me or predetermined. Really cool that it felt real though. Nice job! The music selections were great and I liked the SFX too.
I did have a little trouble sometimes knowing if my bid was the one the auctioneer was referring to or if I needed to click again. So maybe have an indicator saying "You are the high bid" or something. I mention it because one time I had clicked, but it said I didn't bid/win at the end so I was confused by that.
Otherwise it's a really great concept that I haven't seen before and getting the "view time" to see "what's behind the door" is a great idea! Nice job!
Thanks again for playing/rating Untangled, too! And congrats on finishing!
