Very interesting is the

-magic_numbers

!

open a command window cd to your steam/noita folder and first start the game just with like

noita.exe -magic_numbers test 

a file "test" will popup in your noita-folder

have a look at the file - delete your save game (world-folder, player. and wordl_state.sal.... afaik) in

C:\Users\YOURUSER\AppData\LocalLow\Nolla_Games_Noita\save00

then start your game with e.g.

noita.exe -magic_numbers test -config C:\Users\YOURUSER\AppData\LocalLow\Nolla_Games_Noita\save_shared -windowed -no_logo_splashes

(without config it seems you won't be able to use your mouse or do anything)

you can load the game with a defined seed, etc.

also there seems to be hints for coop and i found a string DeathmatchTest

investigated with process_explorer

had not much time to investigate more - it's late and i'm tired - maybe wiser guys have more fun and knowledge how to hack this better ;)

-magic_numbers whatever_you_want
