Well, to help with level construction, I’ve been making a level editor for Resonate.  The level file is actually just a text file, with the level divided into slices that I call segments.   There is one setting for the overall speed of the level, and each segment can be a different length physically, so when playing in-game, your avatar will speed up or slow down.

Based on feed back from Meyitzo, PSPdemon and Dutt, I’ve got it to the point now where it shows a 3D preview of the parameters that the autogenerated level will contain.  It allows for a custom palette, and a variety of setting:

• four visualizations currently supported: plazma, walpaper for the mind, wall paper squared, and Julia Set.  These can be tuned to have more or less scale either length of level, or height of the features
• tunnel and horizion views with custom coloured fog/sky
• camera angle for the segment of left, right or front.
• Custom height based palette, or a rainbow of colours for the default palette

Here are some screen shots of the latest version in action.
