Beating up the bad guys is the name of the game here, as you simply have to clear everyone out in each area before you can move onto the next. Younger children may struggle a little bit, however, as bad guys have a tendency to get themselves jammed on buildings or stuck inside the scenery, so you'll often find yourself backtracking to find a single elusive enemy before you can proceed. The turtles aren't immune to getting stuck either, occasionally getting caught on objects or getting trapped stock still in the middle of the screen, unable to move at all unless you switch to another character.
Fully voice-acted, with a simple enough premise and controls, beyond its idiosyncrasies, the main bulk of the game shouldn't pose too many problems for the younger crowd. That being said, boss fights may cause younger players some trouble, as they often have random spikes in difficulty – for example, an early boss battle with Fishface required some pretty fast reactions in order to win. With the boss leaping up onto a platform and sliding towards you, every time you managed to punch him and knock a chunk of his health off, he'd speed up, until he became almost impossible to hit (and avoid), with fish-related collisions chopping off a fair portion of your health, turning what started off as a fairly simple fight into a fight where you'll want your friends backing you up.
For the collectable fans, each level has a number of hidden trinkets to pick up too, as well as glowing spheres to collect and spend on upgrades for your characters, giving them a new attack, bolstering their health and more. With fifteen short levels to play through, the entire game can be blasted through in around about three hours, perhaps four if you want to hunt out all the collectibles and fully upgrade each of your turtles.
