instructions - The word words for 'stack' and 'blocks' should be the same as for stacking children's blocks. Use the imperative verb form appropriate for speaking to a child, gender unspecified. If no gender-neutral singular/familiar form exists but a gender-neutral plural/formal form exists, use that instead. Be sure to use the same translation of 'move forward' as above.
