makes game recipes more difficult and more complex. but does not add more entities/items and uses the game entities only. main purpose was to make game more challenging but also not to use new items/entities like other mods do, uranium is heavily used. focuses towards end game.

focuses on "expensive mode" only and the recipes by default do not show up in "normal mode" games

most probably not compatible with any recipe changing/overhaul mods.

take this mod as a personal preference, some changes may not make sense.
