I would like to share a recent experience i made with a fresh concept game.
Microsia lets you dive into a plant cell to explore the sound of the microcosm. Within the cell there are a multiplicity of cell particles which you can manipulate to generate music and visual effects. The particles' interplay creates new audio-visual compositions again and again.It is really innovating and relaxing ( it remembers me Electroplankton the first interactive music video program made for the Nintendo DS ).
System Requirements: Windows XP/Vista, 1.8GHz CPU, 512 MB RAM (1GB for Vista users), 64 MB Graphics Card, DirectX-compatible sound card
The demo/game is only 10MB ... let me know if you like it ;-)
