Alleyway
This is just a plain "break the blocks" type of game with nothing interesting about it.

Balloon Kid
If you wanted to see a level-based version of the Balloon Trip mode from Balloon Fight, that's this. Still very tough.

Catrap
A bit of a strange puzzle game where you have to do things like push blocks so you can reach the "enemies" and punch them. I put "enemies" in quotes because I don't think they can hurt you, they're just your goal to reach. Can get surprisingly tricky. Annoying music.

Donkey Kong (1994)
A sort of puzzle-platformer inspired by the original Donkey Kong arcade game. Very enjoyable and clever, and Mario gains some fun moves here. Better than the Mario vs Donkey Kong series which would follow it. A shame the Super Game Boy features are not present on 3DS.
Strongly Recommended
Donkey Kong Land
While its sequels are more closely tied to the SNES games, this one actually features an entirely different set of levels and many different themes, music, and obstacles. However, the small screen space is a real hindrance here, resulting in lots of blind jumps and hidden enemies. The slow scroll speed also means if you drop below the screen before it scrolls downwards, DK gets killed even if there's actually ground below the screen border. I still played through this and got some enjoyment out of it because of its uniqueness, but if I'm being honest, it's probably a bad game.

Donkey Kong Land 2 and Donkey Kong Land 3
While the gameplay may be improved over the original Donkey Kong Land, these two are much less unique from the SNES games. They feature the same level themes, obstacles, and ideas as the respective SNES game, with slightly different level layouts to accommodate the smaller screen. Some levels may deviate more than others to feel a little more new, but overall, I don't really see a reason to play these if you have access to the SNES games.

Dr. Mario
As far as I can tell, there is nothing unique about this version of Dr. Mario to make it worth getting over the 3DS version.

Game & Watch Gallery
There are four games included here, and they have both re-creations of the original Game and Watch units as well as "modern" versions featuring updated graphics and physics with Mario characters, and the gameplay runs more smoothly and is typically more forgiving. The games are Fire, Manhole, Octopus, and Oil Panic. These can be fun if you're into chasing high-scores, but otherwise it won't keep you entertained for long. Once again, sadly no Super Game Boy feature, which is a shame as it looked really nice.

Kirby's Block Ball
I haven't played this much, but it puts a Kirby spin on breaking blocks, so you probably know what to expect.

Kirby's Dream Land
The original! It may be short and lack copy powers, but there's still something charming about this game. The extra mode can be tough!

Kirby's Dream Land 2
This game introduced Kirby's animal buddies! Like most Kirby games, a pretty straight-forward platformer with fun powers.
