Hello! Well, a mod on Oneshot exist and its called Oneshot Aftermath. I had tried to follow the instruction but that does'nt work. Well in any case i think i need to own it on steam. Here the 2 message anyway (Translate from french) "Unable to execute code because steam_api.dll was not found. Reinstalling the program may correct this problem" and "Unable to execute code because vcruntime140-ruby250.dll was not found. Reinstalling the program may correct this problem"

Edit: Oh and my problem is when i have replace the files for the mod, i cant lauch the games.

You'll have to talk to the creators of that mod, since it was probably created for the Steam version, not the itch one.

It is what it seems. Thanks a lot though!

Edit: And thanks a lot for this masterpiece! So good to play. Good luck to your future project!
