From Softendo Download Games:
Mario Forever Advance was made especially for the fans of Softendo Mario Games. It took a few weeks to develop this project to feed the most experienced players. Those who hunger for extreme adventures and longer gameplay will not be dissapointed. This MOD is a stand-alone version allowing you to play at the same scenes as the well known Mario Forever but it's much tougher to get through. On your way you'll meet plenty of poisonous mushrooms crawling through the stages, you'll have to face huge number of dangerous Hammer Bros. and even Bowser Twins as well as very difficult Koopa shooting homing flames, huge skulls of Cheep-Cheep jumping out of water. There are also additional check points to raise your chances to survive. Good luck and enjoy.
