452: Silhouette Mirage
This is probably someone's favorite game, which is weird to us. After the 16-bit era, Treasure kind of split in two. One part released bullet hell shooters. The other had a habit of making technical platformers that are impossibly ugly to look at. Silhouette Mirage falls into the latter camp, with a projectile affinity system that was a test run for Ikaruga's main gimmick.
