Played more of this on my Switch (particularly the Metafight Chronicle version with voice acting) and I have to say - this is, in my opinion, the best Blaster Master game bar none. Even though I feel like Zero 3's got better combat, Zero 2 just feels amazing to play for me (leaps and bounds above any of the other Blaster Master games before it in terms of movement and combat) and the map design is fantastic. The only things that might be a turn-off are the difficulty (much more challenging than Zero 1 but still on the easier side and area maps still spoil the dungeon layouts) and the fact that the game uses a world map to travel between planets and planetoids instead of having interconnected areas like most of the other games (even then, the areas themselves have a ton of room for exploration).
