I was looking for interesting Japan-only SNES titles, and I found this fire fighter game, that is quite fun. It's a very much a multidirectional shooter, except you're shooting water at different types of fire. The fire behaves like different enemy types, there is stationary fire, fast moving fire, fire that duplicates itself, and fire that spawns small new fires. Even the bosses are made of fire. It sounds weird, but it works very well in practice.
