Wow, I am left with such a smile on my face after playing this! Such an ingenious concept and really intuitive to understand.
I'm not even bothered by the short length of the game, it's a perfect little encapsulated experience!
The sprites are so cute and the possessed sheep have this subtle humour about them that is so lovely.
One thing I will say is that you may want to factor in or disable diagonal movements as I accidentally hacked one of the puzzles by jumping past a rock into the fenced area. Easily fixed though.
Wow, this game made my day! Sending peace & love from a fellow Pico lover! :)
