I would suggest also adding some sort of error counting into the mix (perhaps allowing 3-5 lives in total, maybe with bonus lives if you're fast or you get it on the first try). Right now it's a bit too easy to semi-brute force shapes that are somewhat similar. It would also be good to have increasing levels of difficulty. Eventually you could add a leaderboard. As a side note, it's fun to see the amount of humble-bragging going on in the thread right now ;))
