A Raycaster I'm working on using Love2d with GLSL.
WASD to move Space to jump Double tap space to fly Shift to descend Control to sprint(really fast...)
F2 to screenshot F3 for debug menu F4 for debug mode (DO NOT USE IN FULL SCREEN) F11 to enter/exit fullscreen Esc to exit fullscreen/quit
Scroll to change render distance Right click + Scroll to change FOV(zoom) Left click + Scroll to temporarily modify LOD(Level of Detail)
