@leonhard08 remixed my version 8 He added a Koopa but the shell did not move. I've added this. I will add my own Koopa later in version 9 of the original project. Use arrow keys to move and jump. Collect the coins. Jump upon enemies (twice!) to beat them. Want to remix this game? Use the custom block 'createInstance'. Input x and y (and for goomba's the number of blocksthey 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!
