Lasso is an obscure arcade game, developed and manufactured by SNK Corporation in 1982. In it you play a rancher/cowboy trying to round-up his cattle with a rope.
The game generously gives you an opportunity to practise throwing the lasso at the beginning with a “warm-up” screen. Then you have to catch loose sheep and shoot fireballs at attacking wolves… Ah, you can’t make this stuff up… Let a wolf or any of your cattle touch you, though, and you lose a life. Lose all three lives and it’s game over.
If you complete the sheep level, it’s then onto the cow level at a slightly harder difficulty; then the horse level. And so on. Extra hazards, like fire(?) breathing lizards, also become more frequent as the stages progress.
