Hey yeah so you need a full expression (at the least, a start number, operator, and end number) for it to be a valid highlight. Will try to make the instructions more clear for this
Hey, thanks for checking it out! I had the idea for a "zen" mode where you could play forever with no timer. Didn't think of adding lives though. Cool idea.
Would you want separate statistics for these "lives mode" games?
Nice idea and great website design. I usually just use a list on my notes app or Google doc and reset it whenever I need to start over. Might have to try this out.
