@stared Thanks for that wonderful game. I played through all levels some months ago and really liked it. When I saw that interactive quantum link [1] on the front page today, I was reminded of your game and thought some other might like it too.

Thanks again for building it, it was the first time I could actually bring my mind to embracing quantum mechanics :-)

found a bug: if i click next after completing a level before the "you won" screen pops up and subsequently click next level on the "you won" screen i can skip two levels ahead

I was just about to comment the same thing. :)

Thanks for the game. I am playing through the levels and it is a lot of fun. But so far I have not found an effect that cannot be calculated with the classical Maxwell equations in matter.

A single photon QM is basically classical wave mechanics.

My original intention was to do many-photon QM game (and wrote game engine for that). But in development I discovered that even wave mechanics offer quite a lot interesting, and counterintuitive, puzzles.

With one photon there the only thing that does not have a classical analogues is https://en.wikipedia.org/wiki/Elitzur%E2%80%93Vaidman_bomb_t..., which can be easily assembled from the blocks (well, the idea for using a light-sensitive bomb comes from there!).

omg, i <3 love this... esp cool that you included technical details like the amount of rotation caused by glass slabs.
