I am prototyping a game to get a feel for it.
Requirements (to be expanded):
* Hex grid map of a level;
* A character (just an 2d image of a hero) moves in all directions, also using hotkeys.
* camera follows the hero (map bigger than the screen -> player discovers the level)
No polish, just a raw prototype you can build fast and explain me design decisions and alternatives out there ( I am a software engineer myself, but new to the web).
