How to play
Use arrows [↑→↓←] or W-A-S-D keys to move Mario, to jump higher hold the button.
Use Shift/CTRL to Fire/Sprint. Use P to pause and M to mute.
You can play continuously or select a level out of 32 any time you want.
There is also an option to generate a random map. It's an infinite fun!
In this game you are playing the role of the Mario. You are going through the Mushroom Kingdom, surviving the forces of the antagonist Bowser, and saving Princess Toadstool. Mario should reach the flag pole at the end of each level to win the game.
There is a lot of coins scattered around for Mario to collect and special bricks marked with a question mark, which may reveal more coins or a special item when Mario hits them. Other bricks may also contain some coins or rare items so if you have enough time, try to hit them as well. If Mario eats a Super Mushroom , he becomes a Super Mario — he grows to double his size and gains the ability to break bricks above him. If he gets hit in this mode he will turn back to regular Mario instead of dying. If Mario eats a Fire Flower , he becomes a Fire Mario — in this form, Mario gains the ability to throw bouncing fireballs from his hands. If Mario touches a bouncing Super Star (a rare power-up), he turns into Star Mario. In this form Mario is invulnerable to nearly everything and he can kill enemies with a simple touch. This is a temporary form so use your newly obtained powers quickly!
