arrow keys to move, up arrow to jump, a to change weapon, down arrow to attack, when the turquoise thing appears that means your magic is ready. space to use it. avoid spikey black balls, get to the taco, attack the duck, don't take too long when underwater, (at the end of 8 and 7 seconds respectively, if you're touching the taco, you're safe.) at the end, when you fight the boss, only magic and bazooka can hurt the boss, magic has a 10 second cooldown, bazooka has 5 second, and grenade has 2 second.
feel free to use the sprites if you want. the boss magic is just a baseball colored blue with the threads enlarged and moved outside :D
