A bot would only be stopped by this because of novelty. Recaptcha can easily be bypassed by using human solvers, which are available for $1.50/1000 captchas last time I checked. In my opinion, it would be easier to automate this than recaptcha because this uses common elements that don't have nearly enough difference between them to make it a challenge. A solve rate of <5% is effective for spammers. How is this going to stop anything when a spammer can simply cycle through to a game they know how to beat, and fake the mouse movements and timing? Recaptcha is difficult to beat with OCR because it is designed to withstand attacks by OCR considered 'state of the art'. It is impossible to beat with off the shelf solutions. On the other hand, this would be rather simple to automate using pixel matching. The shapes and colors don't change (Take the pancake example, for instance).
