Use arrow keys to move and jump. Hold Space to run. Collect the coins. Jump upon enemies (twice!) to beat them. Want to remix this game? Use the "when I receive startGame" block. Input x and y (and for goomba's the number of blocks they move). X and y and number of blocks are based on a grid of 32 pixels. So x=5 means it is in fact 32x5=160. y starts at the bottom so y=0 means the floor of the game. Give it a try!
I fixed the bug where the death costume target number is 11 instead of 9, then I had to target the costume name to "Mario_hit_32" using hacked/unused blocks and I also changed the Mario speed while holding Space to make it a little easier.
