Really good fun...
I really liked that, it was very challenging, but not so much so that it would irritate you. I just have to ask, what is the music that is playing during it, and can I download it anywhere? Overall:
Good work mate!
The challenges were good and racing against the clock can either mess with you or keep you focused. If you were to continue with this as a series, might I suggest removing the counter that shows how many questions you got right so far and for the memory game with the 5 digit numbers maybe add some variety 4 digits - 9 digits. I really enjoyed this game and hope to see future versions that are maybe a bit more challenging.
But very well designed.
These are the type of games that I love to play!!!
problem with the time
your clock is flawed, it doesn't take into account the hour hand moves minimally when it's not exactly xx:00 hours. ie if it's 1330, the hour hand would be between 1 and 2, while the minute hand would be at 6. Sucks for people who read time just looking at the hour hand :P
