The application should allow for mouse based or keyboard based input to move a character/piece around the app window toward some end goal. Do not try to make anything elaborate, rather think about some simple puzzle mechanic, where the movement of a piece can achieve some sort of simple goal - like following a path, collecting elements or avoiding obstacle(s) to reach an end destination.

KEEP IT VERY SIMPLE

The game could incorporate both visual elements and audio elements (that

signal progress and/or when the goal has been reached)

d. Try to keep the game/puzzle to a single, relatively static scene - or some very simple motion (similar to the projectile motion or even simpler - linear / step-based motions).

** there is only a very limited expectation for interaction (limited to mouse/key presses and related) - 

Example ideas:

i)  Create a simple jigsaw puzzle, or tile sliding game (to re-construct an image)

ii)  A simple platformer with a moving character that moves due to a single click,

or has its movement perturbed by a mouse click or keypress. (static puzzles might be easier, but if not... lerp() is your friend !)
