After completing a puzzle, the "Thumbs up/thumbs down" buttons are prominent, which is obviously intentional-- I assume it is to encourage people to respond.
However, I worry that the responses would be highly biased-- as humans, we react negatively to failure and positively to success. As a result (I would imagine), when nudged to react to a puzzle, the feedback is heavily biased based on the result of the puzzle (i.e., "won" puzzles have an artificially high approval rate, while the opposite is true of "lost" puzzles).
My suggestion would be to make the "continue training" button more prominent. If people are strongly fond or averse to a particular puzzle, they will be more likely to search for the button to provide feedback, anyways. If it's a simple case of someone just wanting to move on, don't encourage a reaction for something towards which the user is ambivalent.
(I am aware the above is poorly worded, but I'm tired from work, so I don't really care. If anyone wants clarification/coherency, ask me tomorrow.)
