Retro Raycaster Fps With Secret Levels

A 90s-style first-person shooter that runs in any browser from one HTML file, with no art or sound files to download. Three hand-made levels and a hidden fourth behind a secret exit. An arsenal from fist to rocket launcher, five kinds of enemy including a boss, red, blue and yellow keycard doors, secret walls you learn to spot, an automap, a status-bar face, cheat codes and a kills, items and secrets tally. One line reskins the whole game.
