Only played for 30 minutes but so far it's really entertaining.
Has a nice good ol' western feel to it with the environments, music and story.

Only thing that aint top notch is the graphics. The use of shaders to make it look a bit like a comic is nice, however grass and plants look really gritty and kinda hurts a bit to look at because of the high contrast in the game. Going to play around with FXAA-injector later and see if i can make it a bit better.

I have no idea how long the game is, but i can imagine its not that long as the price is only ~€15, but I can imagine it's a game you can play through a couple of times without getting bored, because the focus is on the actionfilled gunfights, and they're awesome! :)
