Garden of Coloured Lights  
This game is really fun! I love the graphics and sound effects. I've only reached level 2 twice after playing for hours, so I'd say it's a little difficult. Great game though!

This game is fun! I found myself playing through the 8 demo levels on each of the 3 difficulty settings. The concept of gathering defeated ships is kind of cool. I think the readability of the help screen for the controls could be improved. I wouldn't buy the game, I think it should be freeware.
