I have found an infinite life glitch, I can leap off as much as I want.
After playing through the level and continuing to heal all damage . I got to the part with the giant robot with the Laser beam and it's stepped on me and I insta died and then after it Reloaded I could not heal after, I had four healing packs and it would not work. But , Yes I have been enjoying I just wish I was better at these types of games.
