annoyatron255/Game ? reverse-engineered prompt

Help me turn this into a simple playable game where the main goal is to run away from the bad guy.

I already have the basic C++ project, so please wire up the game loop, movement, input, sprites, and simple graphics so it actually feels like a tiny game instead of a demo. Keep it clean and easy to extend, because I want to add things like mouse support, better input handling, sound, and more game features later.

If it makes sense, also improve the main loop and the helper code so the game logic is easier to work with. I’d like the result to be something I can build and run right away, with the player moving around, the enemy chasing, and the screen rendering properly. If you need to check current docs for anything unclear, feel free to look it up online and use the simplest working approach.
