This game is for bc_, merry klikmas!
I played a little fast and loose with your requests, but I hope its still alright! You mentioned liking euro western more than great american western and i didn't know what that means so i watched "My Name Is Nobody" on netflix and I still don't know but anyway i set the game in a desert with lots and lots (and lots) of cacti. You play as a feller with a rude finger that you can use to poke the villains that surround you. It's got klipart villains and it uses cooltext.com to generate the dialog reactions. a little mno guy will follow you around as well. i used some artistic license on him but i used your drawings so i hope that all works out. oh and there's an explosino when you beat the boss. Oh! and that music you linked. it's made in unity so i can't post the events per se but the source is here if you want it.
controls: WASD to move
mouse to point
shift to sprint
you can beat the banditos by rude fingering them
also make sure you're connected to the internet because it downloads the cooltext in real time
