Toejam and Earl is, well, maybe the most advanced game on Genesis. Let's get started!
Graphics: 10
I Have to give the game a ten for graphics because the palette is quite ranged for a 16-bit game. this is seen clearly in the backgrounds, and Water. the sprites for characters are also quite diverse, and while some characters are choppy (The Devil, and the dentist), many have plenty of frames, Like Toejam, Earl, Fat lady with rude child in shopping cart for no reason whatsoever, and Many Funkotronians at the end.
Sound: 10
So many sounds, so much time. Many of the voices are rather high quality, and the music is nice.
Addictiveness: 9
Because of the Random World feature, the game has a very, very, VERY high replay value to me.
Story: 7
The Story isn't very well explained in game, but in manuals and websites, it makes sense. Basically, you have to help Toejam and Earl collect the 10 parts to their ship so they can get back home. which is a bonus level.
Depth: 9
Random Worlds, many enemies, the secret Level 0, Bonus level at the end, hula girls, and space elevators give this a 9.
Difficulty: 6
The game is pretty hard, due to the hula girls preventing movement, devils constantly poking you, rocket skates driving you off the edge of the stage, the boogeyman which deals high, high, high, high, high, HIIIIGH, High high damage, random fake mailboxes that kill you, hard to earn cash, the fact that you can't breathe underwater until the end, you lose oxygen quick in water, and many other things make this game a 6 in difficulty.
Overall: 9.8
If your goal is to play 35 games before your birthday, make this one of them. you'll get a kick out of this. and maybe laugh till your eyes explode.

I have never actually heard of this game and it does not sound all that bad. For your review, I think the organization was good, you could have had a little but more detail on each section but all on all it was pretty good .

Well I've been stumped. Never heard of this game before, but if it's really all you say it is then I'll be sure to try it out. 

You're starting well with the review you've got there. Maybe next time you can make it a bit longer because you clearly know what your talking about and you shouldn't really have any problem filling the space. Descriptions for each category should probably be over one sentence long. But good start!

Yeah this is one fun game. Great review thanks for taking the time.
