The reviewer made a fatal mistake while reviewing this game. This IS NOT the remake of the SNES Turtles in Time game. It is a remake of the ORIGINAL ARCADE version the SNES version is based off. The Arcade version actually allowed 4 Players; thus, that is not a new function, but it did not have the Technodrome level or the extra bosses. Those were added later into the SNES version.
The reviewer also mistakenly called the Shredder Robot Boss the final boss instead of a mid-game boss, which makes me wonder if he actually knows anything about the game in the first place and isn't just being paid to read a script (poorly, I might add). Why do all these corporations actually think they can get away with half-assed information dealing with topics and videogames the majority of players didn't just play, but GREW UP with?
So in actuality, they didn't remove anything from the game. They accidentally made us think it was a different version that happened to have more content. I think he, along with just about everyone else, made the mistake of thinking this was a remake of the SNES version, not the arcade. In all honesty, I'm willing to bet the vast majority of people didn't even know there was an arcade version, which was a huge mistake on Ubisoft when they decided which version to make. I'm quite positive 90% of everyone who has played this was exposed to the SNES remixed version, not the original arcade. 'Tis a shame too, the SNES version was actually better, oddly enough. O__o
