Now, to start this review, I'm going to state I am far from a fan of the mobile games. I find them decent, however, like Call of Duty, Angry Birds has milked and merchandised because of casual gamers thinking it's The Godfather or Citizen Kane of gaming. I also think it's the sad cause of why the PlayStation Vita's sales are low is likely because of mobile games like this. I don't have a Vita myself (I have a 3DS.) but I know there is at least one game that is better than my favorite Android or iOS game, Jetpack Joyride. 

Now, onto the review. This is a ROM hack for the "NES" that is flat out repetitive. Let's fly in to, "Angry Birds".

Graphics:

Eh....this is the best part of the game because, let's face it, the rest of it is a repetitive extravaganza.

Sound:

The only sound is a repetitive chiptune that wasn't a well written piece of music to begin with. It's the only sound, as stated before, however, it could have had SFX, different music for the title screen and other sceneries. Plus, it isn't the original theme song, which was an okay song. Missed opportunity.

Gameplay:

It is repetitive. Did it have different birds? No. Did it have interesting features like the rocks and the TNT? No. Are the physics flat out terrible? YES. All you are doing is the original gameplay with dumbed down physics. Now, regarding the physics, you are likely saying, this is the Nintendo Entertainment System, it's because of limited power. Well, I'm no expert on power, but didn't the Game Boy have the same amount of power that the NES did? Why I am bringing this up is because of Strength, the Pokémon move was in Gen 1 for the Game Boy. It allowed you to push rocks in your way. Why, couldn't the blocks move? 

Verdict:
It's might say Angry Birds, but it's a poor game with very little effort.

Evil G : I heard of angry birds
the video game but haven't played It. It looks decent enough, reminds me of duck hunt. The game sounds pretty bad but I am going to try It anyways lol. Thanks for the Info.
