Cave Story (Doukutsu Monogatari) is a classic indie sidescrolling platform / adventure game by Daisuke "Pixel" Amaya.
The game's greatest fault, in my opinion, is its quirky default control scheme that cannot be changed through config files or the bundled DoConfig utility.
Cave Story WASD addresses the issue of poor default controls at the level of the game binary. It offers "WASD" or "NES style" controls without requiring any third-party software to intercept and repurpose keystrokes. That is, the changes were made to the game binary directly, as if Pixel himself had designed the controls this way.
The rest of the game remains absolutely untouched. The only thing changed here is what action each key maps to within the binary.
