idk why but whenever i was playing i was hitting enemies and all of the sudden i just teleported underground but i could still hear my self hitting nothing with the lead pipe
please keep this comment alive cause i am waiting for an answer
this is how I beat the game easily:
1.save for the high energy laser. 2.save for cheapest 3 slot ship. 4.save for cheapest 4 slot ship. then the bosses should be alot easier. Good Luck
