Hard agree that the last level sucks SO FUCKING BAD. Even on Easy Mode where every girl gets taken down by a single attack, I Game Over-ed (as in losing all three lives) to the tune of some odd 10 - 20 times at least.Wait until you see the last levels. Literally nothing except death rays, traps and instakill falls that abuse how excessively bouncy and irresponsive the game is. There are some levels with literally 0 girls, all traps.
Awful.
In the end my winning strategy was (still on easy mode) charging up a shot after every single jump to take out the bombers as I moved forward a singular platform at a time, then jumping on top of the girls with rifles to do the quick-fall aerial kick. Even then, I still needed a hefty dose of luck to not get suddenly fucked up the ass by the rotating sparks a few platforms have.
