Just finished it. I really like it. I think the the game is easy to grasp, and requires some skill to get the cows into the barn. Speaking of catching cows, the lasso felt good, and moving lassoed cows felt hefty like it required momentum (I loved it)
The cacti were also a nice touch and added to the challenge.
The art really cute, and super readable. The sound effects and music were similarly fantastic.
My only feedback applies if you choose to update after the jam, but I think giving the player some range so they can choose how far out to throw the lasso might be a cool idea.
Anyway, had good fun, really cool core mechanic, excellent work.
