Drop of Light

Drops of Light is a single player puzzle game that's played on a star shaped web

On the web are what look like coloured beads, these are photons and the puzzle is to move, arrange and combine the photons to produce a specific pattern of colours.

The game is postcard-ware, i.e. It is freeware but the developer would like a postcard so that they know their game is being played and how far it has travelled. Each level gives the user a password which allows them to restart the game without replaying all the earlier levels, the passwords were available on-line too.
