Description

Controls - WASD to move - Left and right arrow keys to look around - Mobile: touch the screen in the direction to move/turn To increase your FPS, use turbowarp: https://turbowarp.github.io/#414675446 This uses an "adaptive sampling" method I created (probably not for the first time outside of Scratch), which uses recursion and interpolation. If two nearby rays touch the same edge within ~1–2 tiles of each other, interpolation is used to increase performance. If a corner is detected, both rays touch different edges, or at least one ray touches nothing, recursion is used.
