Mario: Escape From the Princess

Coding a Game:- Mario: Escape from the Princess

Created by: Sambhav, Grade 6

In this project, we are going to make a game on M.I.T app inventor, a programming software that is quite easy to use.

In general, Mario games are quite easy to play and perform on M.I.T app inventor, but in this game, we will increase the level.

In this game too, it's not Mario that we're going to move, but the Princess and the grass, it will still give the impression that it's Mario who is moving.

Thanks for watching this project and happy viewing!
