Sorry, but not giving the player an opportunity to save the remaining civilians or collect remaining stars... not even a second... after defeating the last enemy, is just wrong.
Fun, but could use more colorful and satisfying sound effects. We need some glass in there, I'm honestly surprised there is none. Oh, and a cat. Hidden off screen in each level, that gets mad and makes noise when you hit it. Sort of like an Easter egg that turns into a challenge after you realize it's there.
The speed and coordination tests could be better. Some people could be very fast but not adept typists, or vice versa. Being able to deal with mouse input inversion is also something that's very trainable. The best tests are not trainable.
Highlighting deficiencies in the jump and movement system is not a good way to add difficulty to a game. Falling for the 30th time because you keep bumping your head is tedious and annoying.
