Consider this one unexpected...
Probably my main issue with Thimbleweed Park was that playable characters couldn't talk to each other while on the same screen. Well, let us never speak of this oversight again, as Terrible Toybox have added just that: cross-character dialogue. I honestly don't think I've ever seen anything quite like that before as far as a content update is concerned, so chalk it up as a win for the good guys.
And as that wasn't enough, there is a new in-game hint line. Call it up from one of the phones, and hopefully Chester will be on the other end.
These updates should already be available on Steam. Additionally, expect to see the game for iOS and Android "later this summer."
