Aventure is a graphic action-adventure game inspired by the old mainframe game of the same name, where you use your joystick to wander around, collecting keys to explore castles, labyrinths and everything in between, whilst slaying anything that moves (i.e. Dragons & Co.) to get treasures.
The game has 3 difficulty settings: Level 1 (Easiest), Level 2: The Kingdom is larger than Level 1, containing secret rooms and hidden items to add difficulty, and Level 3 (Hardest): Similar to Level 2 but all objects/items are placed randomly throughout the Kingdom.
Gameplay revolves around picking up (and dropping) items, hacking your way through dragons, finding keys to open the castle gates and using magic (i.e. reincarnation) in case you get swallowed by failing-to-follow-their-diet-plan-dragons.
