What an awesome submission. I learned now that I need more than 2 measures to think. I had fun trying all the levels and loved that you could just select another if you got stuck/frustrated with one.
Everything is so well thought out and blends together perfectly. Accessability? If you don't get first place I don't know what will. Thanks for allowing to opt into WASD!
The only critique I want to give is: you mentioned that everything was done in inkscape, so vector graphics. If that's the case I don't know why the game has to be so pixalelated with antialiasing issues on high resolutions. I think your "design" or base res should have been a lot higher, scaling down on smaller devices/web.
Maybe I am being unfair as a 3840x1600 user...
