Hi, I am new on the site and I wonder if this detail of Sir Fred has been already described.

There is a problem when trying to throw stones to the octopus in the third screen to the right; most of the times the image becomes full of colored squares and sometimes the game does not respond any more to the keyboard.
In my old days of Z80 this did never happen; must be a problem with my navigator (Chrome) or Operating System (W 8.1) or with the Spectrum Emulator used in this site.

Apart from this, the game Sir Fred is WONDERFUL!!!! Thank you very much for making it accessible in this way!! :)
