It is definitely styled like the 8 bit metroid. The environments can get a bit repetitive and drab in style but so far the enemy design is intuitive and reminds me of a cross between metroid and mega man. The bosses are big and colorful and definitely a highlight. The gun effects are also pretty cool and more like mega man boss weapons (but with unlimited ammo). The glitch weapon is one of the coolest I've seen and does interesting things when used on enemies.
