We're so glad you liked it! Likewise, we thought your game, since everything the player did was pre-planned, was absolutely great at handling difficulty while still producing a really satisfying take on the theme. Fresh air, indeed!
Funnily enough, we haven't tried doing it multiplayer ourselves yet. We usually use dogs 1 and 4 to push the sheep around manually and dogs 2 and 3 as like stationary diverters to funnel them in certain directions. It's especially helpful on the bridge level. We imagine a speedrunner might be able to make pretty good use of them as well, and along those lines, we imagine a 2-4 player attempt would be either epic or hilarious or both and many other things as well, lol! :-)
Thanks so much for playing!
