@PhoenixBoltS That's odd, arrow keys should do the job. Did you try clicking the canvas?
You also might need to refresh... I didn't have the time to properly handle game overs or make an intro screen, so the game will start while you're reading the instructions.
It'll throw an alert when you die, but the game will still keep running. Refreshing should allow you to move/look around again.
There's a lot of things I could've handled better if I would've had the time, but unfortunately that wasn't the case :)
