This game is really not polished and some levels are a bit meh-ugh (looking at you factory) but idk nothing really beats the feeling of dashing and slashing through this one. I could play MMZ all day and still not get bored, it's just really nice to play through every once and a while (especially with how short it is). I think this is the Zero game that fulfills that urge the most for me, which makes it, despite all of its flaws, the best to play in my personal opinion. Objectively though, I do feel like Z2 or Z3 will be a better experience for most people.
