Use the arrow keys to move,don't touch the lava. There are two characters, one is called speed quick which runs fast and the other is jumping demon, that double jumps, use w, e, r, and t all together in order to double jump. each of their jumps needs time every time you use jump. Stay on the platforms and do not get burnt by lava or killer sprites, every ten seconds, the lava with rise, then fall back down and all over. So time it and your good. GOOD LUCK! :)
WAIT, THIS IS A NOTE FROM 2021, November 21! my first ever official project create even before jark. I don't want to mess up the memories so I will leave this
