In this game, you are a robot navigating through maze-like sprinkled with enemies. 
The primary objective is to outmaneuver enemies, strategically use boxes to block enemy attacks, and eliminate hostile turrets with a lasers 
and reach the portal (goal) which progresses to the next level and eventually win.

WASD keys handle movement. Laser firing is executed with 'K' (westward) and 'L' (eastward) keys, and J is used to reset to the game.
