URL: https://overfuture.dev/en/products/wondy-world/ - 6 worlds - 8 piece families in the editor - Android, PC and web builds of the game - 2014 → 2026 from Google Play to Unity 6 The game · Eternal Spring ## What Wondy World is, and who made it Wondy World is our own 2D platformer, built in Unity by OverFuture and Androtiyas, our founder's video game brand. It has six worlds, quests, items that change your abilities and a creative mode. That mode is what sets it apart: players build levels with the game's own pieces, test them and share them. The campaign and player-made levels follow the same rules. - 2014 Released on Google Play. - 2022 Pulled from Google Play: the reviewer couldn't get into creative mode without an account. - 2026 Migrated to Unity 6 and on its way back to Google Play. Need player-created content in your game, or got an old project you'd like to bring back? Tell us in the form. - **Genre:** 2D platformer, adventure - **Creative mode:** Built-in level editor - **Engine:** Unity 6, C# - **Worlds:** Six - **Versions:** Mobile, PC and web - **Code:** 65 scripts, 18,498 lines - **Status:** Released in 2014; being re-released - **Development:** Androtiyas and OverFuture Challenge 1 · Creative mode ## An editor that won't save broken levels A level editor turns the game's internal rules into a tool. If placing a piece is hard, nobody creates anything. If nothing is validated, impossible levels get shared. Wondy World's editor works on a grid. The map starts at 70 by 15 cells and grows with what you place. Before you drop a piece, the editor warns you if that position isn't allowed. There's also a rule for saving: at least 25 coins and 10 enemies. The editor keeps count on screen and, if any are missing, warns that the map won't be published. We explain it in [How was the Wondy World editor made? (in Spanish)](https://overfuture.dev/blog/como-disenar-editor-niveles-videojuego-unity/). - **Result:** No shared level arrives empty or half-finished, because the rule is checked before publishing. - **For your project:** If your players create content, validation belongs inside the editor, not in moderation afterwards.

Challenge 2 · Saving and sharing ## A whole level in a single line of text To share levels between players, the format had to be small and easy for the game to read. Each level is saved as text: first the background and sound, then each piece with its id and its cell. The same line works for editing and for playing. The game reads it, puts each piece in place and decides whether to open the map in edit mode or play mode. The pieces are grouped into eight families: character, items, buildable, decoration, traps, events, enemies and extras. Each family sets how many of its pieces a map can hold. - **Result:** A level travels as a line of text and opens the same way for editing or playing. - **For your project:** Saving content as simple data makes it easier to share, version and moderate.

Challenge 3 · World progression ## Six worlds, quests and items that change how you play World 1 · Tutorial World. Grass: the first world, where you learn to play. World 2 · Eternal Spring. The grass biome with giant mushrooms and extra levels. The 2014 recording never reaches this world, so we've assembled it here from its background, ground and pieces, next to its menu card. World 3 · Desert. Pyramids, cacti and bees. World 4 · Tundra & Ice. A snowy forest and ice platforms. World 5 · Happy Candy. Sweets, lollipops and flying enemies. World 6 · Final Fire. At night, with falling fireballs. Each world changes the scenery, enemies and blocks without changing the controls, and each level introduces a new goal, obstacle or reward so the next step makes sense without explanations. Items change abilities such as health or speed and open up other ways through a level. Quests and the leaderboard give players reasons to come back. The cards above are the game's own menu cards. - **Result:** Six worlds, each with its own identity but the same controls; the first one teaches you to play. - **For your project:** World-by-world progression lets the game grow in instalments without redoing what came before. The result · Happy Candy ## What you play in Wondy World Frames from a 2014 recording: some menus were still in English back then and the coin counters were test values. - [](https://overfuture.dev/en/products/wondy-world//productos/wondy-world/img/wondy-world-seleccion-de-mundo.webp) World selection, with the shop and the quests. - [](https://overfuture.dev/en/products/wondy-world//productos/wondy-world/img/wondy-world-seleccion-de-nivel.webp) Level select, with the stars earned on each level. - [](https://overfuture.dev/en/products/wondy-world//productos/wondy-world/img/wondy-world-nivel-superado.webp) Level cleared, with a score to share. - [](https://overfuture.dev/en/products/wondy-world//productos/wondy-world/img/wondy-world-arena-con-abeja.webp) The desert, with a bee next to the pyramid.
