Handler notes

Free Steam Game. Edit: the game has been updated with native split-screen for 4 players now.
Split-screen setup guide.
2 players max can connect to the same game. Create a private group in the first instance and join in the other with the room code, make sure both instances are connected to the same server region in the game settings, use your main mouse cursor to navigate the menus, Steam needs to be open when launching.
If you use keyboards and mice after all the instances have launched, resized and positioned correctly, press the END key once to lock the input for all instances to have their own working cursor and keyboard, you need to left click each mouse to make the emulated cursors appear after locking the input. Press the END key again to unlock the input when you finish playing. You can also use CTRL+Q to close Nucleus and all its instances when the input is unlocked.
Known issues: All instances read from the same registry path, horizontal split-screen has issues cause the game has trouble with its UI elements in ultra wide resolutions.
If you can not connect the instances make sure both instances are connected to the same server region in the game settings, also try deleting HKEY_CURRENT_USER\SOFTWARE\Kitka Games\Stumble Guys using the Windows registry editor app before launching the handler, the instances should have a different in-game name, you can also try deleting the save folder in AppData\LocalLow\Kitka Games.
