It probably sounds petty but I am still mad about not being able to use B skins on the vita version and haven't played the new update.
Probably not entirely because of that, but to a good deal I do.

Still fucking up the C skin for chicken because I choke in the IDPDHQ like a dumbass.
Otherwise I got everything. Still upset that Frog and Skele dont get their own character slot, gold weapon, and crowns once you get them for the first time.
