Play as a rotund dog who isn’t that great at locomotion to finish your neighborhood walk. You have to stay on the sidewalk path while at the same time trying to keep from toppling over. Difficulty increases both between levels and within the levels themselves.
Use the left and right arrows to shift the character’s position while using the a and d keys to maintain balance, mostly after shifting position. The left and right arrows displayed on the screen provide feedback on how well the character is balanced. Ideally the game is randomly generated (if possible). There are only three mistakes allowed before it’s game over.
I don’t know if there are other mechanics/features that the player can be introduced to in later levels, but I’m considering it.
