This hub links to the level list, diamond locations, and element-traps reference so a player can move from a stuck puzzle to the right section in one click.

How the Forest Temple chapter fits in the walkthrough
Fireboy and Watergirl 1: The Forest Temple is the first chapter in Oslo Albet's cooperative puzzle series. The Steam release on AppID 5084260 ships the Forest Temple chapter as a standalone title, with the rest of the series (Fireboy & Watergirl 2: Light Temple, 3: Ice Temple, 4: Crystal Temple, 5: Elements) available as separate entries and not bundled into this AppID. The walkthrough structure for the Forest Temple chapter is therefore a single-chapter progression from the first level to the chapter exit, not a multi-chapter campaign. The Forest Temple chapter acts as the on-ramp to the rest of the series: it introduces Fireboy's water weakness, Watergirl's fire weakness, the green goo and poison pool mechanics, lava avoidance, and the simultaneous-button cooperative triggers. Once a player clears the Forest Temple chapter, they can carry the same control layout and the same element-rule instincts into the Light Temple, Ice Temple, Crystal Temple, and Elements sequels.
Single-player vs two-player co-op walkthrough approach
The walkthrough for Fireboy and Watergirl 1 The Forest Temple runs differently depending on whether you are playing solo or with a co-op partner. The element rules, the level order, and the diamond gates are the same in both modes; what changes is the path through the simultaneous-button triggers. In two-player local co-op, one player runs Fireboy on WASD and the other runs Watergirl on the arrow keys, sharing one keyboard on one machine, and the simultaneous-button triggers become a coordination exercise. In single-player mode, you control one character at a time and switch between Fireboy and Watergirl using the keyboard layout, and the simultaneous-button triggers become a self-timing exercise. Both modes use the same Forest Temple level order and the same element rules.
How diamond collection gates the Forest Temple walkthrough
Diamond collection is the central progression mechanic in the Forest Temple chapter and shapes the walkthrough structure. Each level hides a fixed number of diamonds, and the level exit only opens once every diamond in that level has been collected. Missing a diamond blocks the exit and forces a backtrack. The Forest Temple chapter uses diamond collection as the level-gating mechanic. Some diamonds sit on fire-safe platforms only Watergirl can reach, some sit in water-safe sections only Fireboy can reach, and some sit behind green goo or poison pools that both characters must avoid. The element-traps page explains which character can collect which diamond, and the diamonds page ties that to the per-level gating.
