NAMCO Galaga Arrangement PSP Full Playthrough Hard
A game I've had as a kid on my old PSP though I didn't remember very much of it at all when I played it through this time. I did remember that you could get abducted to power up your ship which is incredibly helpful on the harder levels. I didn't remember the final boss having so much health, I had to survive the longest time with no lives left wondering when the stupid moth was ever going to die.
I may also play the other "Arrangement" games Pac Man, Dig Dug, and Rally X in the future.
