Hi! We're working on the next update right now, but we're still maybe a few months off. The next patch will be an entire alternate path of meeting all the characters in a different order with new dialogue for each of them. But the current state of the game will let you meet and fool around with all four characters, just without as much freedom who to meet when you want. We were hoping to to have more progress by now, but 2020 had a few last punches to throw at us.
Thanks for the interest in the game :) We'll try to make as awesome as we can!
