a,w,d. it's a bit finicky, and yes, blank spaces do exsist, it's not a bug. grass block=safe, no hazard spike=dangerous hazard. lava=dangerous hazard ice= safe, but you keep sliding until you fall off the block or your momentum is gone. and turning wont affect the sliding direction. flag=goal, hit the word goal to advance to the next level. rain&snow= safe, distraction fog=w.i.p. feature, breaks game. all the coding is by me.
