HOW TO PLAY: Walk up the steps and kill the dragon. Collect the collectibles and jump off. Go through the green door,take the 2 crystals and the yellow key and go through the yellow door. Collect everything and run through the stairs! :D
I knew you would run into that lava. :D Use your jetpack(press the c button) and fly over the lava bricks. Jump on the conveyor belt and grab the rest of the crystals along the way! (well it's automatic,and you might miss some so go around again and collect it.) Then you've finished!
