Super Mario Adventure

It's not quite like the classic Mario Bros. but it's very close to it in all things graphics and sound. The advantages of this free online game compared to the original: the background is deeper and more extravagant, other enemies, a new and interesting design of coins and graphics much better than 8-bit, there are frequent save points, which were missing completely at the completion of the original level leads to a new background of the next level, which changes more frequently than in the original. Cons: You'll get killed here as many times as in the original if you're not a super-trained Mario player who has thousands of hours of gaming experience behind him.
