May i suggest being able to upgrade your weapon for different cinematics and so the turtles bounce more when you swing. And can the last hammer be Chuck Norris's Hammer? It looks the same as a normal hammer (very small) but when you swing it it dents the floor and the turtles go flying everywhere.
ayesha how about you get some balls? No seriously get the 4 balls and put them on the pedestals the first 1 is at the left puzzle the 2nd one is to the right after getting two just place them and put the levers in the position the sign says
Twilightblade have you thought that the walkthrough was wrong? Or that it includes the place you need 20 medals for? And AssassinInformer it took you 6 hours to get to the ocean area... seriously? It took me (and everyone else) under an hour
