Descend the Pyramid (#GM20 Jam)

This game was made for GameMaker's 20th anniversary game jam.  The theme being "20", I created a runner who must descend a pyramid in maximum 20 seconds. And as an illustrious person would have said: "From the top of this pyramid, 20 years contemplates you"... (ok, maybe a little more).Also make the best score: 20/20 and beat the distance record...  What GameMaker has been doing for 20 years. Good…
