I just downloaded it. You have a maximum amount of bounces and need to complete each level under the maximum amount. You use your left and right arrow keys to move Mario around the level and you need to reach the green star to finish the level. There are weapons you can collect and you can select the weapon by pressing the number keys 1,2 or 3. To use the selected weapon you need to hold down the Ctrl key. Then there is the usual coin pickups, mushrooms and enemies to avoid. There is also 2 difficulty settings, easy and hard.
The first 2 levels are very easy but then it becomes much harder as you only have a certain amount of bounces to complete levels. He is very easy to control in the game.
I would rate this game as 3/5.
