Attempt To Do Game Development

I was about to go to the Game Development on Open2Study. But turns out, the class doesn't start yet. So I downloaded Clickteam Fusion 2.5 Free Edition on Steam and did a bit of stuff. I then tried to make a platformer game, but I couldn't figure out how to make my character jump after many attempts, so I deleted it. However, I did figure out how to make the character move left or right and make a floor.
