This game can be played on either a computer or tablet. The goal of the game is to get the yeti to avoid falling balls and collect watermelon slices. On the computer use the left and right arrow keys to move. On the tablet tap one of the arrows on the screen to move in that direction. Love and favorite.
most of the code for making falling objects can be found here https://scratch.mit.edu/projects/215293210/ (although the objects in that project go to the side instead of down but you can just switch the y axis and x axis if you want them to go down)
