This document contains source code for a 2D Super Man game created in the Ring programming language. The game has the following key elements:
1. A main game loop that initializes the game engine and game state and runs the game.
2. Sprite and text objects to display the title screen, instructions, and in-game elements like the player character and score.
3. Logic for player input and movement, collision detection with walls on the map, and interaction with enemies and powerups.
4. Functions to handle the game state, open doors when scoring thresholds are met, and end the game if the player runs out of energy.
