You , good sir, are a true hero of your generation. Being born in 1987, I wasn't fully exposed to all the hubbub around the Spectrum, the Atari, the Commodore 64, etc.
However, I still spent my childhood mostly playing the good ole C64. I've played hundreds of games, and this brought back plenty of memories. I've been playing this game for about ten minutes now (haha :P) and I've been trying to figure out some things. I refused to use the hints, though, as it completely draws away from the experience and I grew up playing games like this and now it's just second nature.
I've done quite a bit of programming in my time as well; Hell, I've been on a C64 since I was not even four years old! :P
I love this though; this is what gaming is all about. Abstract square tunes and large pixellicious blotches made into barely-recognizable figures.
Well done. You've made the best flash game ever. ;D
Now make more. Muahaha.
