Yes, I'm aware of the WASD trouble for some people and I've noted this for future development of both new games and possible updates for this game. Thanks for your input!
It's a very simple thing, but almost no web game does it, which makes them unplayable on many computers. I shouldn't have to switch my keyboard layout to use a website :(
You don't HAVE to support it, but accessibility is nice, especially when it comes at virtually no cost except awareness (it is not supported because people don't know it exists).
