I suggest going to F95zone.com and looking for the game there. People usually post full game saves and mods for stuff like invincibility.
But honestly, the game isn't hard, you could just play through it, you'll enjoy the reward more.
thank you I played it normally I was having trouble with the boss it's all about saving ammo
That part’s easy. Let every enemy just rail you. It doesn’t deal damage. This way, the only enemy you need ammo for is the gym boss and the plant monsters at the end of the current version. And also the one time you have to shoot barrels.
