HOW TO GET THE TWO ENDINGS: First ending: Just walk into the beam at the last level. Secound ending: Walk up to the beam, but DO NOT enter it, wait for a few seconds and the beam will dissapear, allowing you to walk past it. You can defeat the final boss by jumping into the middle of the gems without hitting them or jump over the gems and fire a spike in mid-air when you above them (just be sure you have one left), you will be frozen in mid-air but you clone won't be and will fall to his death (be sure you evade them after your clone is dead.)
