I can't move with the keys, only with the mouse. Am I alone ?
the game only works with WASD so the problem might be that you're using the arrow keys, if you are using WASD though im not sure what caused it
Actually, some browsers just dont let you input keys on some games, unless it's fullscreen (or even then saddly)
I had same problem with an other game on Unity. I could play using Firefox instead of Chrome
