Love the western theme! (Biased)
Great work, on this submission. The music and graphics fit the gameplay well. I particularly like the whirling the lasso animation.
I think I would have liked to be able to grab the money bags with the lasso, as opposed to having to wait for the bad guy to grab it. I think that could add some more strategy to this game.
I also enjoyed the later on levels, with the upgrades and the larger groups of enemies it's very satisfying to swoop up A whole posse of no good baddies all at once.
Great job!
