Ganpuru - Gunman's Proof (Japan) [En by Aeon Genesis v1.03] ROM

Gunman's Proof was developed by Lenar and published by ASCII in 1997. It was not released outside of Japan due to the SNES being phased out in favor of the newer Playstation.
If you took the gameplay of Zelda: A Link to the Past, mixed it with old-style westerns and added a liberal amount of the funny dialogue and music from the Earthbound/Mother series, you'd end up with this charming game.
Two meteors have fallen to Earth, one containing an alien sherrif, named Zero, and another containing an alien outlaw, named Demiseed. Zero asks to inhabit the player, a young boy, so he can defeat Demiseed and thus your adventure begins.
As said before the gameplay is almost exactly like a Zelda game, only instead of a sword, you start with a pistol. You travel through the overworld defeating enemies, gaining money so you can upgrade weapons and equipment and delving into dungeons to defeat the boss and gain the dungeon's treasure.
The game is full of personality and rarely does it take itself seriously. As you approach the forest one of the enemies, an arachnid-man, glides down from a tree on a thread of silk, it then snaps and he falls flat on his face, he gets up, dusts himself off, then attacks you. The music is composed very well, quite catchy, and is absolutely befitting of a western.
The only problem is that the game is ridiculously easy. You're sure to never have a problem beating it, which, combined with it's rather short length, it's over all too soon. Strangely, there is a "lives" system. Though you can save at any time, if you die three times it's game over, but you may then just load your last save.
