Please wait. Bleeding edge experimental technology of the future is being loaded,
which may take 10 or 20 seconds with no apparent progress.
Be patient. Do not make hasty keystrokes. Breathtaking letters
in sixteen brilliant colors and HD resolution beckon from the other shore.

from README:
The game runs rather slowly in the browser (fastest on Chrome).
Savefiles are prone to corruption on the browser,
e.g., when it's closed while the game is still saving progress.
Hence, after trying out the game, you may prefer to use a native
binary for your architecture, if it exists.
