Graphics: Lets start off with graphics, the graphics are the same as Firered generally but more have been added in here and there, the sprites from other generations have been used with care and not just slapped on, There are numerous custom tiles which are used in the story line, so far as i know there are no visual bugs.

Sound: I haven't played Firered in a while but this sound is tune to my ears, I think its custom but i can't really tell, nevertheless if you don't speed then it keeps you going along the way, the sounds go together with stories and plots very well creating a strong bond between them.

Addictiveness: This game has a unique plot and the fact that there's about 4/5 new Pokemon in  every route kept me catching them all, its very addictive, trust me. Although it does depend on what you personally are looking for in a Pokemon game, still, this game is TOO addictive.

Story: This game's story is pretty unique, the fact that it has custom maps to continue the plot really works well, your constantly in an adventure or a quest so there's no dull moments, this games story... It's nearly indescribable.

Depth: Due to it being only in Beta this game goes up too the fifth gym but there is still a lot to do in it. 

Difficulty: Not very difficult at all unless you start off with your team of 6, then your in for a rough ride. 

You did OK for your first review. I see that you already master the right structure for it, which is a good start. However, you need to get deeper into details to make a better review. What made the sound so great? What about the plot: what makes it so unique?

Also, since this is a Pokémon game, how does it compare to other games of the series? You mention Firered briefly but not much.
