Hi there, thanks for commenting.
I'll have to find that stream you mentioned, I had a C64 back in the day but I don't remember a sheepdog game - would love to see it.
In terms of picking up Too Many Sheep, it's my 4th version of this game so there's a very good chance I'll pick it up again but maybe in a slightly different form as I build up my skills.
The other three versions have been called "Sheep Game" the first two are no longer available, as they were Flash games back around 2000 / 2001. But the third version of the game is on Itch and Steam.
I'll be sure to swing by here and comment once a new version is available.
