Jurassic Boy 2 (NES)

Oh boy where do I start with this one? This particular bootleg is a complete rip off of Sonic the Hedgehog. No assets are taken from existing games, but the game play is 100% identical to Sonic and the first level seems to resemble Green Hill/Emerald Hill. This game was also later ported to the GBC, have you played this title before? Also there's no Jurassic Boy 1, just like many other bootleg games this one is just numbered for no reason.

I've just started playing the GB version... Oh boy it looks much worse than the NES version! I don't think I've played the NES version before but the physics in the GB version are horrendous and Jurassic Boy can't roll in the GB version. I'm on level 3-2 now, I'm surprised I even made it that far...
