Doom By Numbers is a planned 10-map Doom 2 WAD, with each map having its own unique theme based on its map number in the WAD. For this NaNoWADMo preview the first map, "1 Tough Cookie", is included. Choose between the difficulties HNTR/HMP/UV to choose how many monsters to fight during the map, or set the difficulty to ITYTD to turn off monsters and have a casual stroll.

Requires GZDoom, tested with v4.11.0.
