Mario Great Adventure 2
This game is actually really fun! Once you get past the ear piercing sound effects that is (or you can turn your computer down, whichever works)!
The jump and move physics have been nailed, it feels like a Mario game for sure, but it has it's own unique flair. The Beach Ball balance. You will see!
So, the aim of the game is to collect all the possible points of the level. This includes collecting coins, mushrooms and squashing Goombas and Koopa Troopa's!
There are quite a few levels to play through and even an overview world map screen to give it that tinge more Mario goodness. Enjoy, and stay out of the water!
