Fun but broken game

This game is set in a westerns setting mixed with demons, it a fun turn based shooter where you play a story divided into scenarios where you travel around on a map and can get money/loot between story missions , unfortunately this game has some serius bugs that can make it impossoble to complete a scenario and it seems there is no fix for it, i got to the end of the second scenario and got a black screen when i tried to enter the last fight and there is not solution to be found that could help, it's a big shame as i had great fun up til that point, buy at your own risk.
