You need a Windows computer and Visual Studio 2022. I have moved all the dependencies to be part of the project itself (in the includes and lib folders), so I hope that you will not need anything more than that. Just open the project in Visual Studio and click the run button to build the game.
Mario is on the left and Luigi is on the right. To move Mario, use the A and D keys to walk left and right. Use the W key to jump and use the S key to shoot a fireball. To move Luigi, press the left and right arrow keys to walk left and right. Use the up-arrow key to jump, and the down arrow key to shoot a fireball. If a player gets hit by a fireball, they lose some health, as indicated by their health bar. Once all a player’s health is gone, the other player will win. Press the space key to restart after someone wins.
