According to the private newsletter, the second episode of Kentucky Route Zero will be released mid-May:
Act II
Our goal for Act II has been to release it by the end of April (
our general development goal is three months per act). All this exciting but unexpected work setting up distribution, going out to IGF, and troubleshooting for a larger number of players than we anticipated took up a lot of our time in the last few months, so we're pushing the release of Act 2 back a few weeks, into mid-May.
It's looking really good though, and we're anxious to have it out in the world. For the next few weeks, until the release, we'll be posting a small/weird screenshot from Act II on our Twitter and Facebook pages every day. So thanks for your patience, and keep an eye out for those!
