Well I think I'm doing okay in the event. Mad Hatter lvl 6 (ready for 7), White Rabbit lvl 4 (ready for 5), March Hare lvl 5 (just leveled up so not yet ready). Caterpillar is 4 ear hats short from being Welcomed. I'm 41 gems short of being able to get Cheshire Cat - so I'll get him before the event ends, but wish I had him now to help with Caterpillar! I think I'm going to review my gem strategy to see if I can get him in time to help with Alice...
As for the event, I was like everyone else and accidentally tapped a few Ravens earlier than intended. However, I've managed to get to rank 40 with 224 ravens. I'm hoping to stay in the top 50 to get an NBC chest - I wasn't playing when that event happened, and haven't bought any chests yet, so hopefully I'll get a character!
Did anyone else notice that ALL the event ear hats were redesigned with today's update?! I think they all look much cuter now!
