Some constructive feedback: - The language randomly seems to switch to something else ("porta") - Even if you're faintly familiar with the problem (like me), it's hard to gauge the actual goal of the game. For example I didn't recall if a door being empty is good or not. - The coloring seems not very helpful. Red for the chosen door? Red is usually associated with something bad. And the colors for opened and still closed doors are not easily associated with their state. A simple bitmap or even a text would say much more than those colors. - The statistics give a lot of numbers that aren't meaningful, and don't show the meaningful ones. In particular the absolute counts of how often was switched are hardly of importance. It's about the ratio of correct decisions - in particular that number should be split into switching and not switching decisions.
