TMNT wasnt THAT bad. The water level could be completed after maybe 3 tries, people always fuck up on that cuz they forget where the last bomb is located(which I admit was faggotry on the developers side). There were tougher games I think. I never played silver surfer but after watching a youtube vid ofit, Im glad I never did. One hard ass game I couldnt get through on NES was Street Fighter 2033. Dont know about that game? Look it up.
