Goonies II is a strange case in many ways. While there was a game based on the Goonies, it actually never got a home release outside of Japan, only appearing in the west on the Playchoice-10 and VS systems in the arcades. Then, as if that wasn't odd enough, Konami decided to produce a sequel to it even though there wasn't a sequel to the movie. It changed up the format quite a bit, taking cues from games like Metroid; you explore a very large environment, uncovering clues, finding upgrades for your character, and eventually rescuing all of the Goonies from captivity. Even at this early stage, though, Konami definitely showed off the quality in their games with some detailed visuals, smooth animations and a quite good soundtrack (including a rendition of Cyndi Lauper's "The Goonies 'R' Good Enough"). It may not have had a corresponding film, but Goonies II was a classic game just on its own merits.
Shoot-em-up style games were already a pretty well known genre well before the NES hit the scene, and it continued to get quite a few throughout its life, with a lot of them being unremarkable ports of arcade games with pretty basic gameplay and minimal variation, so I tend to glance over a lot of them. Sqoon is a relatively early one for the NES, but its design is anything but basic - there's quite a lot of mechanics that you'll have to juggle to get far. There are the usual waves of giant enemies to blast away for points, but other sea life appears too - orcas are harmless to you, but will eat up any people you blast free by bombing buildings, crabs drop gold bricks you can collect and turn in for points, and the odd sea slug will drop a magical necklace if you bomb it enough times, which grants a 1-up and a chance at a bonus stage. In between all of this, you'll have to free captured humans, touch them to bring them aboard, and once you have nine of them, drop them off on the "floating island" that appears (one by one, with the B button), which is the only way to replenish your constantly dwindling oxygen supply and gain powerups to upgrade your weapons. The aforementioned gold serves as a more efficient means of doing this - all you need is one live human and a gold brick to get the island to appear again, though this will only refill your oxygen and not upgrade your weapons (which makes it a better option when you've already hit max upgrade). Sqoon is chaotic and outlandish even by shmup standards, but undeniably unique and quite a lot of fun once you get into the swing of it.
A fairly popular game in its time that isn't talked about much these days, Astyanax was quite a sight to behold on the NES. Large sprites with a surprising number of animation frames, elaborate and detailed backgrounds, some imaginative (and gruesome) boss designs, and gameplay slightly reminiscent of Castlevania. The player gets a choice of three weapons, though the way they operate is slightly odd - some get more damage from simple swings but cause the player's magic attack to consume more or less of the gauge in return. A relatively fun game to play through regardless though, and the imagination employed in its visual design alone certainly makes it worth a look for fans of obscure gems.
If you watched a lot of cartoons in the '90s, you might remember Samurai Pizza Cats - a dub/recut of the Japanese anime "Kyatto Ninden Teyandee" that ramped up the silly humor to the nth degree. I also got into emulation around that time, which led me to learn that there was a game tie-in to the show, so it quickly became one of the very first Famicom games I emulated. It does a good job recreating the feel of the show, with animated cutscenes between stages and before boss fights, several recognizable characters as bosses and recreating most of the protagonists' iconic special moves. Even the Rescue Squad appears, allowing you to traverse various obstacles the main cast can't - punching through blocks, tunneling through dirt, swimming through the water at great speed or even flying for short distances. While not an amazing game on its own, the fact that it captures the feel of the show so well and has such nostalgic factor will always earn it some points in my book.

A relatively unique and well-crafted puzzle game by Irem, where you play as a snowman-esque character named Kickle who can create ice pillars and freeze enemies with his breath to turn them into cubes. Said cubes can then be pushed into the water to create floors, or pushed into other enemies to eliminate them, or ricocheted off of springs or hammers to redirect their motion (though they can easily clobber you as well, so you must be careful). Your goal in each stage is to collect the three "dream bags", though as in any good puzzle game, this quickly becomes a daunting task - avoiding enemies, being careful not to trap yourself and setting up pillars in the right time and place to avoid hazards are all skills you will have to master (especially in the bonus stages, unlocked after completing the main game). There are boss fights too, which require some quick movement and reaction speed to overcome.
