Sonic the Hedgehog Harder Levels is just a hack of Sonic the Hedgehog but with more badniks more traps and more adventure. This game would be recommended to advanced Sonic the Hedgehog gamers that want more adventure out of Sonic games.

GRAPHICS
The Graphics on the game are the same as the original Sonic The Hedgehog game except this time You are able to use the Sonic the Hedgehog 2 technique known as Spin Dash which gives you the upper hand on the game and might make it slight easier for you.

SOUND
The sound in the hacked game is pretty much the same as the Original game nothing much different about it.

ADDICTIVENESS
The game can be addictive because if you keep dying in the game you might try as much as possible to get past it and move along in the game it might take you a long time to complete it and that might be what makes the game addictive.

DEPTH
The depth in the game has gotten bigger because it's more difficult than the original Sonic The Hedgehog game so it should be more bigger.

DIFFICULTY
In my opinion I thought the game was very difficult and very hard to complete it might take a while for someone to complete this game.

OVERALL
Overall I thought the game was brilliant even thought I might have died a lot in the game and had a few Game Overs I still enjoyed it and I would recommend it to more advanced Sonic the Hedgehog gamers.

Well the grammar was a bit off but you got the main points down.i never even completed the original i had on sega genasis,so this would kill me.id probably get annoyed very quickly
