When I stumbled upon this game, I thought it looked really cool! Metal Sonic is one of my favorite Sonic characters, so I knew this would be fun. And it  was! I'll go over the basics first.

Graphics get an 8. I think most of the animations for Metal Sonic are done really well! He animates smoothly and it looks great. The animations seem to mimic the ones used in Sonic 4: Episode Metal. And that's not the only time inspiration is take from that game, either. There are a few things I don't like about Metal's graphics, such as the Super Sonic sprite, and the goal plate art, but I think they're done pretty well.

Sound gets a 7. I noticed that the Spin Dash sound effects sounded a bit more hydraulic. Other than that minor difference, I didn't notice any other sound modifications.

Addictiveness gets a 6. The idea of this game is fun, but there isn't that much that has changed. The only differences I noticed were a double jump. Which, again, is taken from Sonic 4: Episode Metal.

Story gets a 3, mostly just because there isn't really a new one. It's just Sonic 3&Knuckles, but with Metal Sonic.

Depth gets a 4. As I said, I is just Sonic 3&Knuckles. Having a double jump/midair dash does add minor exploration, but nothing other than that is worth noting.

Difficulty: 5. Again, just Sonic 3 &Knuckles. Not incredibly hard.

Overall, this game gets an 8.5. It's a fun little mod/hack that is certainly interesting, it seems like Sonic 3&Knuckles: Episode Metal. I think you should give it a try, even if it doesn't have too much to offer.

I seen this game an thought it was a hack. Guess I'll have to try it out thanks.
