WASD keys don't work, everything else is fine. Not playable when its hardcoded to use keybord (no need, add mouse buttons) for keys that dont work.
Could you give me some details to which browser and OS you're using? Because those keys do work (Chrome, Firefox, Opera on Windows or Linux)... :/ Maybe if you're using IE/Edge or Safari (or Mac in general) there may be issues as those are relatively difficult to support, and difficult for me to test personally.
