This is a quite bonkers platform game! No other way to describe it in one word! Your task is (as usual) to get to the end of the stage (the little flag a la Super Mario Bros), but if you try the orthodox way of playing you'll find that even the first level is impossible! What the game enables you to do is to change the functions of a block type. So, say you point at the wall and then at some pointy spikes. Then voila! you can step on them as if it's a wall! There are some quite interesting implications of this mechanism and the game makes good use of it. So have a go!
