Nice one!
As a fan of the Zero series I've beaten all four games at least 3 times each on all difficulties. And I gotta say, this is REALLY accurate. Out of everything in this game, I couldn't find a single thing that didn't act like the original enemy that the sprite was based on, except for one. Those purple spiked enemies actually CAN die after two or three hits from the Z-saber, even though it's more of stun effect where they stop moving, then start up again a couple seconds later. Other than that, the enemies were better than I had expected. Plus customizable controls, a new storyline, and new missions, even if they were kinda reminiscent of the old missions, this game is the best and most accurate MMZ game I've seen as of yet. (Not counting the original games themselves, of course.) All in all, nice job. I hope to see the next one soon.
