The pics are all from the next episode, part 29 (release March 24).
The upcoming two episodes, 29 and 30, will be a bit longer than usual (7-8 minutes), and also contain an Overseer battle each, and lots of different story arcs and some other action as well.
The plans for part 31 and 32 are then to try a bit shorter episodes (around 5 minutes), but having more action with way longer Overseer battles in them, to see what the viewers prefer.
Then I plan to try a mid season Cliff Battle (The Cliff 8) that's shorter (around 5 minutes) but with almost only action in it (like The Cliff 3,4 and 5), and see how the viewers like that. The viewers will still know what's going on in The Cliff 8, and what's on stake, from watching the previous Stickworld episode.
I'm Not going to announce it ahead of release though, as that as usual will give people unrealistically high expectations of some 30 minute long video that takes half a year to make or something like that. They will simply see The Cliff 8 popping up instead of The Stickworld part 33, and hopefully enjoy that.
