I'm not sure if it's working right for me on Orion Version 1.0.3 (142), WebKit 624.1.2.19.2. I type my word, hit "Enter," and I still get the hint to press "Enter."
It would also probably be more effective to not change the mechanics between the starting hit and subsequent ones. Instead of automatically starting after typing "hit," the user should have to hit "Enter" as well.
