For the pixel hunt bit, you could use Left Alt+Left Shift+Num Lock for MouseKeys options. It allows you to move the mouse with the Numpad and you can adjust the speed in the options.
It appears this game is in desperate need of an update to keep people playing. If Terry is still active, please update this game. There are already many good ideas in the comments and half of them should be easy to add such as a new room, more actions, and cat editor to allow for more colors.
