The feature in question was probably the Splatoon-like world painting (blood/water/dirt/burn effects) which can be pretty neat. While the characters and dialogues are still placeholders, there's a whole new tutorial, simple puzzles to do in the house and patented Rat AI as well as clones which can be pretty funny. Might not be worth a whole featured video on your channel but a playthrough will surely get a chuckle or two. Thanks for checking in!
