One of the classic shmup for Game Boy, Nemesis is a fun title. It has its flaws, mainly frequent slowdowns when the screen is full of enemies and bullets. The game is also fairly short, only levels that are all accessible from the title screen. The graphics are good, so are the musics, in Konami’s fashion. I’m still looking to get the second installment, but it’s pretty hard to find a CIB copy with a reasonable price.
