... it in HTML local storage(Can erese it with erase all cache and cookies in your browser...)
What is not working:
1. Sound and music volume control
(Once you turn off in the menu you cannot turn
back on any sound just if u erase all cookies)
2. Quit menu option(it figures why not... XD)
3. Function keyboards(F1 to F12) are not working.
The script itself is opensource, so you can rewrite
from scratch change and edit levels and graphics,
to make your own game!
Have fun
