IVAN

IVAN Android brings the classic graphical roguelike Iter Vehemens ad Necem to touch-first Android devices while preserving the original game, art, and unforgiving spirit.

Explore a dangerous fantasy world in a deep, turn-based adventure where every choice matters. IVAN features advanced bodypart and material handling, multi-colored lighting, rich equipment interactions, and emergent gameplay that makes every run different.

Built for touch
• Six direct-action categories: Directions, Context, Items, Character, Move, and System.
• Context-sensitive actions are surfaced where possible.
• Hold a direction to keep moving.
• Numeric prompts use an on-screen keypad.
• Menus and equipment screens use large, readable touch targets.

Map and camera
• Pinch to zoom from a close tactical view to the complete rendered map.
• Hold and drag the game canvas to pan around the map.
• Moving recenters the camera on the player.
• Create, edit, and delete map notes at the selected tile.

Readable mobile interface
• Responsive portrait and landscape layouts separate the game view, stats, messages, and controls.
• Readable story, menu, inventory, prompt, help, and map-note text replaces legacy keyboard-sized overlays.
• The Character category includes the classic paper-doll equipment view.

Mobile options
• Move the directional controller to either side in landscape.
• Hide Android system bars for an edge-to-edge view that respects camera cutouts.
• Enable or disable vibration feedback.

This is an unofficial Android adaptation maintained in a public community fork. IVAN is free software, and the original game and its contributors remain credited in the source and game. This port is not endorsed by the upstream project. Android 8.0 or newer is required.
