Fireboy & Watergirl 4: Crystal Temple

Fireboy and Watergirl 4: Crystal Temple is a platformer lets two players guide elemental heroes through a mystical temple packed with puzzles.

Fireboy masters fire and lava, while Watergirl navigates water safely. Team up to grab gems—red for Fireboy, blue for Watergirl, green for both—then hit your colored exits. Explore 40+ tough levels featuring crystal portals that warp characters, blocks, or objects between linked gates, often hinted by light colors.
