Escape skips the intro; Enter advances pages and selects native menu choices; choose New Game, an available episode and difficulty. Arrows move and navigate, Space jumps, left Alt fires and right Control changes weapon. Escape opens the native menu, P toggles native pause. Held on-screen controls support phones; use landscape fullscreen for more room. Zoom/Pan/Fit enlarge the view. Tab reaches view controls, then the page. The upstream installation guide is linked inside the importer. Original shareware and full game files retain their own license.

Saves
Escape → Save checkpoint → slot writes a native level-start checkpoint. Load restarts that level and difficulty; position, health, score and inventory are not retained. Four slots and settings stay in this browser when storage is available. Stop preserves written checkpoints and exits natively; it does not save the current position automatically. Page Pause freezes time and audio. Original files remain local and can be stored separately for the next session. Clearing site data removes local files and checkpoints.
