Thanks for the comment. I did not know I had to add everything in the build folder.
I've added a zip file with everything in it.
Hope it works now.
Thanks again !
Thanks for fixing it! A very cool idea. Shame not to have some sounds, they would not only add mood to it, but also some they would help a bit. I don't know, for example having a sound that plays when you're about to run out of time, and a different one when you hit the wrong cell, would give more feedback to the player. It's quite addictive, though!! :D
