Hey,
Thanks for taking the time to try the game and give notes :D. Totally agreed, we need more diversity on sheep, I'll add once I have time, changes to the mass and speed and hopefully we'll have different visuals as well.
I also agree that the intro screen is probably a bit confusing, I found myself doing the exact same thing :).
If I get the chance, I'll also add a switch to change between artstyles.
