It's difficult for me to call this a triple trouble fan-game, it's more-so an expansion pack for sonic 3 & K, while that's absolutely not a bad thing. It does come at a cost of stripping triple trouble of a lot of its unique identity.

And when comparing the level design of 3&K to triple trouble 16-bit, I'd say the genesis game wins pretty handidly.

Still, this is an excellent 2D genesis-style sonic game all the same, the team did a wonderful job with it and I can't wait to see more of their work!
