First Person Shooter in gawk

After seeing TheMozg's awkaster project I thought to myself (yet again) "I could make that better, right?".
So during easter of 2020 I started programming and came up with this first result.

Controls

key	action
w/s	forward/backward
a/d	strafe left/right
j/l	turn left/right
TAB	move minimap
~	toggle shading
ESC	quit

Here's a static image of the result:
