Game concept on graph paper

My game proposal, Unboxing, is a game about quick reflexes and survival. The player controls a white square in a monochrome environment. The player square is located inside concentric square boxes with one single hole in each box. Throughout the course of the game, the boxes grow smaller, and the player has to click on a direction button to escape through the hole in the current box (randomly located at either its top, bottom, left, or right) before the hole becomes too small for the player to escape. Gradually, the speed rate at which the boxes become smaller increases, and it becomes more challenging to make a good decision in time. The game ends when the box is imprisoned by a box, but it could go on forever since the boxes have random directions and the player square’s speed should match the boxes’ shrink speed.
