Cool idea! Was fun to figure out what was/if there was something wrong with the badges and having to lookout for something new every day. Speaking of, is the date always the day you are playing on? :o If yes, cool, if no, I would suggest adding the current year next to it so people won't have trouble calculating how old attendees are in the future. ^^'
The art is great! Loved all the different characters and how you could tell their vibe just by looking at them and the little interactions you have with them. The paw is also a really creative idea, but it was difficult to aim with it at times. The game was also bit easy tho but that could be changed by adding more things to check or a time limit before con goers in the queue get angry. ^^'
