playing the frist a koopas revenge is like playing nes metroid, what i mean is that you know there is a better sequel that fixes most of the mistakes from the original game.
a koopas revenge is by no means a bad game, however a lot of errors from this game were fixed in its sequel, like for example koopas gameplay feels a lot more slippery here, there are more bugs, and the level design is not much memorable, and looks like one from a rage game like i wanna be the guy!
for the time this game was released it was impressive, but today having its sequel, there is not much reason to play the frist game.
