A block moves back and forth. Press space to place the block. Try to place the block above your existing stack of blocks (your first block can go anywhere.) If you do not place your block perfectly, then it will get smaller. The block moves faster as your stack gets higher. Press c to toggle between color modes (white and rainbow)
Inspired by an arcade game and by the White Tiles 4 game mode. This uses custom blocks, but is otherwise 1s1s. (You never have two blocks running at the same time.) My best score: 26
