This script is about done. I got the idea from the mouse pressing post
to code it this way instead of with key presses. The galley can be used for a bonus feature. It can be used to display pictures from the game. The images can be locked and the thumbnails can be turned off too. I have done a similar script in the Renpy Visual Novel Engine. I think it is excellent that Solarus has the power to make visual novels with mouse controls.
The art is from opensource sources. I somewhat modified some of it. I will release the credit info for the graphics when I release the script.
