Instruction clarifications

Just a couple of things in the instructions.

• I assume long space button means spacebar? Should we just put spacebar or is there a reason for the different nomenclature?
• It might be clearer if we say "the same as the one that appeared two numbers before it" instead of the current wording. Personal opinion thing, though.
• Also, minor thing, it might be easier if the bottom said "Click here to begin" instead of just "click here"
