Not bad, I really like the concept. With a bit of bughunting, some sounds and ironing out the graphics, I could easily see this one on the Greatest Games list.
You wouldn't happen to still have the source files so you could some day rework it (or possibly release it on GitHub or something so others can rework it)?
You did random generation 2-3 years before it became popular, but since it's popped up into the mainstream now, I believe now is the perfect time to get Genesis v.2 out.
