 ## World
 
-- [ ] Single frozen biome (alike frozen tundra)
+- [x] Single frozen biome (alike frozen tundra)
-- [ ] No structures (beside caves, probably)
+- [x] No structures (beside caves, probably)
 - [ ] No void world
-- [ ] Permanent night
+- [x] Permanent night
-- [ ] Hardcore Darkness (i.e. no light = pitch black world)
+- [x] Hardcore Darkness (i.e. no light = pitch black world)
 - [ ] Permanent storm starting at day 2
-- [ ] Tough As Nails mod (temperature regulation + thirst)
+- [x] Locked at hard difficulty
-- [ ] Locked at hard difficulty
 - [ ] Higher mob spawning rate
 - [ ] No mob spawning before day 3
-- [ ] No blazes or thermal foundation blaze variants
+- [ ] No blazes
+- [x] No thermal foundation blaze variants
 
 ## Progression
 
-- [ ] Not allowed to use oil, in any form
+- [/] Not allowed to use oil, in any form
-- [ ] Lava pumping from Nether using drilling rig
 - [ ] Other planets provide meaningful outputs via drilling rig
-- [ ] EIO Farming Station is lowered to early MV
+- [x] EIO Farming Station is lowered to early MV
-- [ ] No DML
 - [ ] No fancy metal furnaces
 
 ## Transportation
 
 - [ ] No energy sources beside GT-native ones and Nuclearcraft reactors (no solar panels, no TE dynamos, no DE reactors)
 - [ ] No energy distribution beside GT-native ones (for instance -- no EIO energy conduits)
-- [ ] No resource management solutions besides GT-native ones (no ME networks, no EIO item/fluid conduits). Bulk storage (think drawers and barrels) are allowed.
+- [ ] No resource management solutions beside Logistics Pipes (no ME networks, no EIO item/fluid conduits). Bulk storage (think drawers and barrels) are allowed to come from any mod.
 - [ ] No "magic teleportation stuff" (Ender Chests, Dimensional Transcievers), unless:
     - it's an EIO Telepad
     - they are used to tranport between the Nether and Overworld, and have a positions that of a vanilla nether portal (identical y, 8-scaled x and z)
