Use WASD or arrow keys to move the player. A/D or left/right arrow keys move the player left or right. Press space or up arrow key or W to jump. S, the down arrow key doesn't do anything. Watch out for the red, aka lava. The pad that is not red allows you to jump higher if you are on the place. The number on represents the level you are on.
Thanks for Fuelvin's video for helping me create this platformer. Scratch 3.0: How to Make a Platformer Game (Full Tutorial). URL: https://www.youtube.com/watch?v=MAjobdDNqKY. It's my first platformer made, so I wasn't expecting it to be perfect. There are only three different levels.
