One level for 'advanced' Boom compatible ports. Probably it is my vision of nuts.wad. It's easy to play and fun. You need to have modern computer (Core2Duo+ or similar) and good optimized port with support of hi-res textures in wads and music in OGG format. GLBoom-Plus 188.8.131.52+ is STRONGLY recommended. Do not use PrBoom-Plus 184.108.40.206 or earlier. "SkyBox" sky mode and "Fog Based" sector light mode (available in prboom+ 220.127.116.11.test) are recommended and do not forget to enable in-wad hi-res textures. (it's ON by default) WARNINGS: 1. (G)ZDoom has strange issue with speed. It's 1-2 fps when monsters are sleeping. After awakening it's more or less good, but still 4-20x slower than glboom-plus. 2. Eternity and Boom 2.02 have some issues with tall patches. 3. Classic PrBoom and PrBoom-Plus before 18.104.22.168 have no support for hi-res textures in wad - do not use it. MUSIC: NoMeansNo - "1985 - You Kill Me" - Long Days. Hope it will not be banned because of this 24 years old song.
