So Metal Sonic in Sonic 3 & knuckles

It's an interesting hack using Metal due to its abilities.

Graphics 8: I grew up with this game it looks great despite being nearly 30 years old. Metals graphic look good but the sprite for when you gain a continue looks off, also there's no sprite of it when you enter the bonus stages.

Sound: 8 I love the soundtrack, its stuck in my head since I was a kid growing up in the 90s. The music did sound a bit off at times, in the special stages & some zones where the sound would get quiet or lag.

Addictive 6: I'd go back to it just to get all 14 emeralds & finish with solo Metal etc.

Story hasn't changed from the original, stop Dr Robotnik.

Depth 6: Aside from playing as Metal, not much to offer unless you really want to explore the game. Using it was fun but movement felt a bit slippery with Metal, especially in the super form, also the dash jump sometimes didn't register & I'd miss a jump.

Difficulty 5: S3&K isn't a hard game, even the final stages can be cleared with practice & watching the boss patterns.

It was a fun hack & hopefully Metal will be in other Sonic games.
