Raycaster level editor

Demo I made of a very simple level editor for a 3D ray caster game.
CONTROLS:
In map editor:

Arrows - move cursor
Hold X + left/right arrows - pick tile
Hold C + move cursor - paint tiles
Once PLAYER tiles is selected, press C while holding X to spawn player on map

In first person mode:

Left/right arrows - look left right
Up/down arrows - move forwards/backwards

I originally started making this as a custom level maker for a first person shooter like DOOM or Wolfenstein 3D but I had to move on to other projects.
