+# Smoke-Test-Checkliste
+
+> Smoke Tests werden nach jedem Sprint manuell auf einem echten Android-Tablet durchgeführt.
+> Ziel ist kein vollständiger Test, sondern ein schnelles "Geht es grundlegend?" vor dem Zeigen an die Kinder.
+> Neue Sprint-Abschnitte werden jeweils zu Beginn des Sprints ergänzt.
+
+---
+
+## Basis-Tests (jeder Sprint)
+
+Diese Tests werden bei jedem Sprint-Abschluss durchgeführt, unabhängig vom Inhalt.
+
+- [ ] App startet ohne Absturz
+- [ ] Kein Freeze oder schwarzer Screen in den ersten 5 Sekunden
+- [ ] Musik spielt beim Start (ca. 60% Lautstärke)
+- [ ] HUD: Back-Button sichtbar und funktionsfähig
+- [ ] HUD: Musik-Toggle funktioniert (an/aus)
+- [ ] Performance: Keine sichtbaren Ruckler beim Scrollen/Navigieren
+- [ ] Touch-Targets: Alle interaktiven Elemente mit Kinderfingern erreichbar (min. 48dp)
+- [ ] Offline: Spiel funktioniert vollständig ohne WLAN/Mobilfunk
+- [ ] Kein Netzwerk-Request im Hintergrund (DevTools / Android Profiler prüfen)
+
+---
+
+## Sprint 1 — Proof of Concept
+
+Ziel: Erster spielbarer Raum (Empfang/Reception), Drag & Drop einer Figur, ein interaktives Objekt.
+
+- [ ] Empfangs-Raum lädt ohne Fehler
+- [ ] Figur (Häschen oder Kätzchen) ist auf dem Bildschirm sichtbar
+- [ ] Figur lässt sich per Touch aufheben (Drag-Start)
+- [ ] Figur lässt sich an beliebiger Stelle loslassen (Drop)
+- [ ] Figur kehrt nicht automatisch zur Startposition zurück
+- [ ] Interaktives Objekt (Blume) reagiert auf Touch (Animation oder Sound)
+- [ ] Position der Figur bleibt nach App-Neustart erhalten (Save/Load)
+- [ ] Keine GDScript-Fehler in der Godot-Konsole
