Is this possible to do?

I want to create a game which is similar to doodle jump, but as you know there's only so much space in a canvas, so is there a way to make the canvas and image sprites reappear above the player so that the game wouldnt end?

I'm sorry English isn't my first language, so I have trouble when I'm trying to explain something. So basically, I'm making a game, which has similar mechanics to doodle jump: Doodle Jump: New Record 113k - YouTube

So, as you can see in the video, the character keeps on moving up in the map.

If I do this game on the App inventor, at some point the character will reach the top edge and the game will end, which is not something i want, so I'm asking if there is a way to make it so that the map never ends and the character constantly has new places in the map to jump up to.

I'm really sorry if I haven't explained it well enough, but this is just an idea, i have no code yet, so I'm asking about this, before I start programming.
