well, level 5-2 is completed, but it comes at a price, i lost my re-record count. it reset to 7 about halfway through level 5-2 when i accidentally re-recorded over the entire thing and then used a save state to bring it all back.
anyway level 5-2 is absolutely insane, as you'll see. this shit is virtually impossible to do in real time, it's virtually impossible even at 50% speed. If anyone questions why i use frame advance for a movie like this when slow speed might suffice, shit like this is the reason. (plus collision detection abuse)
anyway the boss. another one that i kill faster than you'd think possible. he's invulnerable for quite a few frames even after the screen stops scrolling and he starts shooting you, unlike the eyeball/anus boss i didn't have to START shooting on the frame AFTER he becomes vulnerable, so i just had my first shot hit him on the first frame he can be hurt.
