I am listing this as a web bug although strictly an oversight:
1) I know you have provided the letters (or characters) to tap (which I hardly think is necessary on a computer on the web version and is in fact slower) BUT one can not only use the characters as there is no “space” provided, so “NorthAmerica” can only be answered by as shown (which is wrong), so I do in fact have to use the keyboard. So the characters only serve to give away the answer not save any typing.
2) I have just completed a level and it has flashed up the progress bar to say “Course Completed” this in NOT true as I still have other levels I have not started. Level completed yes, but not course.
