SPOILER ALERT IN COMMENT - Be aware.
A really beautiful game that definitely makes the brain have to work. I did indeed get caught out a few times not knowing what to do, I looked at the walkthrough below on a couple of bits and kicked myself for overlooking a few things. Have a browse at my playthrough video if you like. The only things I found off were the fullscreen mode didn't quite work, but it was fine and didn't cause too much of an issue. It worked fine on the mac. I loved the game, I thought it was interesting, challenging and beautifully executed in terms of art direction. LOVE the sheep... (Spoiler Alert: It's a shame they all died lol) I would love for it to have more of a narrative/story. The game left me wanting to play more. Nice job!
