Never played the original but saw it a lot as a kid. It really feels liek a concept game, an arcade game on a console. The music is nice, the gameplay is really cool, even though now we could have both joystick used for moving and aiming. The graphics are colorful, enemies have a distincful design. Now on the bad side, the story is just blend, I had one moment where I cared for the characters, the rest is just going along with the stages of going "pew pew". It's a good game for 10ish USD, if the original caught your eyes but you were never able to play it
