Decent game
I have played a few times now. My main complaints:
1) Why no saving on Newgrounds?
2) The minigames are pretty slow and don't make much money. This is really frustrating when you're in the later levels and need a lot of cash to try again (especially when you get shot after one bullet).
3) The whole concept of being forced to pay to play is annoying, it would be nice to be able to return to earlier duels to get more money.
4) Minigames cost too much to buy (I'm not a fan of the minigames in general).
But, the concept is nice, the dueling engine in nice, the artwork is nice, the references to famous cowboys is nice, and the game is a lot of fun. Well done!
