Fireboy and Watergirl 1 Forest Temple levels follow the single Forest Temple chapter from Oslo Albet's original 2009 Flash release, with roughly 30 levels confirmed as the developer-of-record count on the Oslo Albet series site. The Steam release on 2026-09-01 (AppID 5084260) reuses the Forest Temple chapter as the launch content for the standalone Steam build. Diamonds gate every level exit, so each level feeds directly into the next gate. A final Steam-specific level count is Not announced as of 2026-09-06.
Forest Temple chapter structure
The Forest Temple chapter is the first and only chapter in Fireboy and Watergirl 1. Each level builds on the same dual-character cooperative layout: Fireboy and Watergirl share the screen, each character solves the half of the puzzle they can survive, and both characters must reach the twin exit doors at the same time to clear the level. Element hazards (water pools, fire pools, green goo, poison pools, lava) decide which character can stand where, and diamonds sit on the routes between those hazards. Per the Oslo Albet series site and the 2009 Flash-era developer-of-record record, the Forest Temple chapter runs as a single linear sequence from level 1 through the final level. The Steam store page for AppID 5084260 confirms the Forest Temple chapter name as the canonical launch content for the standalone release on 2026-09-01. The Steam Community hub threads reuse the same level numbering when players describe Steam version puzzles.
Where the Forest Temple chapter sits in the series
Fireboy and Watergirl 1: The Forest Temple is the first title in the Oslo Albet Fireboy & Watergirl series. The Steam release is the standalone Steam version of the Forest Temple chapter; the sequels (Light Temple, Ice Temple, Crystal Temple, Elements) ship as separate chapters and are referenced only to explain the autocomplete spillover where search engines pull sequel names into Forest Temple queries. Series sequel levels do not appear in the Forest Temple level list.
Level-gating diamonds and hazard progression across levels
Every level in Fireboy and Watergirl 1 Forest Temple is gated by collecting the diamonds placed on that level. The diamond counter sits in the corner of the level layout; both characters must reach the twin exit doors with the level's full diamond quota to advance. If a character dies in a hazard, the level restarts without resetting the diamond counter, so partial diamond progress persists across attempts within the same level session. Water-safe diamonds (cyan) can only be collected by Watergirl; touching them as Fireboy triggers an instant death on water-themed diamond tiles. Fire-safe diamonds (red) can only be collected by Fireboy; Watergirl dies on contact. In addition to the water and fire pools that drive the Fireboy / Watergirl element split, every Forest Temple level includes some combination of green goo, poison pools, and lava. Both characters die on contact with any of these three hazards, so neither Watergirl nor Fireboy can stand on them. Designers use these shared hazards to block routes that must instead be opened by pulling levers, pushing boxes, or stepping on pressure plates in cooperative trigger sequences.
Steam vs Flash differences in the level list
The Steam release of Fireboy and Watergirl 1 Forest Temple levels reuses the 2009 Flash-era Forest Temple chapter level order as the launch content. Modern-resolution rendering, Steam achievements, Steam Cloud, and controller support are added by the Steam build without changing the underlying Forest Temple chapter level list. Specific Steam-versus-Flash feature changes beyond what the Steam store page lists are Not announced as of 2026-09-06. Per-level minute-by-minute walkthrough text is not published here; if a future per-level page is built, the diamond coordinates and exact hazard placements for each Forest Temple level will live on that dedicated child page.
