This game, Super Mario Land, you're Mario going on an adventure to rescue the Princess, what is exactly different this game, your saving Princess Daisy from the evil alien known as Tatanga. A different twist from the original storyline.

The Graphics:
The graphics for this game isn't the best graphics on the Original Game Boy, it pretty bland, but for a 1989 game, it's not that bad really. All I can say, the backgrounds in the game is well done on this game.
I give this game a 7 out of 10
----------

The Sound/Music:
The Sound effects of this does have that classic effects and some parts of the sound effects we know from Super Mario Bros. Other than that, not a whole lot to explain about the sound effects
For the music on this game is really great, with a different song with each world you traveled and a boss music level and when you face the boss in that world, the music is well done for this game that was released at it's time, that and the star has a pretty song on there as well.
I give the Music and sound a perfect 10 out of 10
----------

The Addictiveness:
The addiction level for this game is not that high, mostly the game is a little bland and difficult (which I'll explain below), but despite this, the game does get pretty addicting, mostly if you die, you have the urge of playing again and again and again, which I can say can get very addictive.
So I give the addiction level a 7 out of 10
----------

The Story:
For the Story, like I mentioned earlier, this is the 2nd game in the Mario Series that the main final Boss isn't Bowser. The story goes that Daisy happens to get kidnapped by an evil alien known as Tatanga, and Mario has to travel through 4 different worlds to get to Tatanga and rescue Daisy. Although you're not sure on what the backstory is and how Daisy in fact got kidnapped.
I give this game a 6 out of 10 (mostly due to the lack of a backstory)
----------

The Depth:
They isn't a whole lot of Depth in this game, with only 4 worlds and with 3 levels in each level, but at least they're a lot of bonus levels in.
I give this a 5 out of 10
----------

The Difficulty:
The Difficulty of this game is really hard, even with a total of 12 levels, those 12 levels are very hard, but once you're used to playing this game, the game is pretty easy to play. Some parts of the game is easy at times and other times, it's a challenge to get through.
I give the Difficulty level a 7 out of 10
----------

Overall:
Overall, this game is really interesting to play, do I recommend this game, I have to say that this game is really great to play on, so I have to say that yeah, this game is recommended to play, that is if you want to try this game out for yourself.
For the overall score for this game, I give it a 8.8 out of 10

A really good review! I enjoyed it. Having said that, you should develop your points more 'it's pretty bland'. Well what's bland about it, you know? I'm just giving some constructive criticism. If you develop your points a little more, I reckon you could do some great reviews! 3.5/5.  

Very good review! Nice and detailed. I like it! Keep it up!!
