Thank you Sophia,
I am using a fade in transition during the intro. It is on purpose. I can shorten this animation (it lasts 1.5s).
I don't understand why the game is so slow. I am using particles for the snow, the fireplace and the smoke. I am also using shaders for instance the fog. May be, particle effects are not well supported by the browser. Depending on your browser you have to activate the hardware acceleration in the options (for instance opera: in parameters then system paragraph). Please, feel free to download the right version to try it in better conditions.
There are 6 different endings. You found one of them :) When you select continue (condition is to have more than 1 life), you don't have to follow the intro again. If you see again the intro, it is a bug! During my playthrough and tests I didn't get this bug.
Actually choosing the direction is not the final feature. I did'nt had the time to implement the polished one: the cat has to move on the choosen button and jump to select it.
Again, thank you for your kind words. I am sad your try was not smoother. I worked hard on the art and the ambience. So this is an issue that the game is that slow.
