Game Concept

Una Aventura Inesperada (An Unexpected Adventure) is a grid-based puzzle game developed for the Nintendo DS using C and devkitpro. The game challenges players to navigate through five increasingly complex levels while managing limited movement resources and answering quiz questions.
The game was created by Juan José Gómez Simón (version 0.8, December 2020) as a puzzle game that combines strategic movement with educational elements.

​
Story and Setting

Players embark on an unexpected adventure through a tile-based world filled with obstacles, enemies, and challenges. The journey is framed by cinematics:
The game begins with a three-frame opening sequence that sets the stage for your adventure:
  • CinematicaInicioF1 - Frame 1
  • CinematicaInicioF2 - Frame 2
  • CinematicaInicioF3 - Frame 3
These cinematics are displayed when the player starts a new game from the main menu (source/main.c:908-910).
Upon completing all five levels, players are rewarded with a closing cinematic:
  • CinematicaFinalF1 - Frame 1
  • CinematicaFinalF2 - Frame 2
  • CinematicaFinalF3 - Frame 3
The ending sequence celebrates your successful completion of the adventure (source/main.c:751-753).

​
Core Objective

The primary goal is to reach the exit tile (meta) in each level while adhering to strict movement limitations. Each level requires:
  1. Strategic planning - Plan your route with limited stamina
  2. Obstacle manipulation - Push boxes to clear paths
  3. Enemy elimination - Remove enemies blocking your way
  4. Quiz completion - Answer educational questions correctly
Running out of movements before reaching the exit results in failure. You must restart the level if you cannot reach the goal.

​
Level Structure

The game features 5 distinct levels with increasing difficulty:

Level 1

18 MovementsIntroduction level with 3 quiz questions (Pregunta1-1, 1-2, 1-3)

Level 2

​
Quiz System

Between levels, players must answer quiz questions correctly:
  • Two answer options displayed on the bottom screen
  • Touch screen selection (source/main.c:956-960)
  • Binary evaluation - correct or incorrect, no partial credit
  • Immediate feedback - success screen or failure screen
The quiz system is implemented in CrearDialogo() function (source/main.c:939-975) which displays questions and validates answers against the correct option.

​
Restart System

Failing a level triggers the restart system: 
// From source/main.c:674-678
if(esJuegoReiniciado == false){
    CrearDialogo(PreguntaFallidaBitmap,2);
}
esJuegoReiniciado = false;
GenerarNivel(nivel1,HUDBitmap,MOVIMIENTOS_NIV1);
Players can also manually restart using the restart button on the HUD during gameplay (source/main.c:220-233).

​
Visual Feedback

The game provides several visual indicators:
  • Stamina Bar - Green bar showing remaining movements (source/main.c:809-814)
  • Animated Sprites - Player, NPCs, and enemies have 2-frame animations
  • HUD Display - Bottom screen shows game information and restart button
  • Dialog Screens - Full-screen images for questions and cinematics
Key Success Metrics:
  • Efficient movement usage
  • Strategic box placement
  • Enemy elimination
  • Quiz accuracy
  • Level completion time
