It has a good plot, pacing, characters, setting, and some fun historical facts. You must defeat 3 bad guys using various Western techniques and objects. I liked the puzzles in this game better than in the author's previous game Dynamite Powers.
This game is very similar to the previous 4x4 Galaxy. It is a procedural roguelike with items and combat. It's pretty addictive leveling up your character and gathering gold.
