It's extremely trivial to complete but it's still kinda neat. Cool presentation, especially for a Flash game. Remember much more fondly playing this (along with all the other Bart Bonte games) when I was very very young, and this does seem like the sort of game that a kid would get more out of, but that doesn't really make it bad per se. Just very easy.

The included song is very nice, and certainly the main appeal here, but you can listen to it outside of the game.

As for the game itself, all you're doing here is moving the mouse roughly in the direction of a bunch of particle effects. Very occasionally you have to avoid a couple red ones. Gets old even before the single short 4 minute long song is done playing.
