Allure of the Stars 

Press '?' for in-game help and/or read PLAYING. The game lags on any browser except Chrome, but you can download a fast native binary. If the game window is too large for your screen, zoom out (Control-minus). Press NumLock if numpad erratic or use other keys or mouse.

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)
and you are limited to only one font, though it's scalable.
Keyboard input and saving game progress requires recent enough
version of a browser (but mouse input is enough to play the game).
Also, savefiles are prone to corruption on the browser,
e.g., when it's closed while the game is still saving progress
(which takes a long time). Hence, after trying out the game,
you may prefer to use a native binary for your architecture, if it exists.
