■ New Features

Numeric mod settings


Numeric mod settings can now be adjusted with the keyboard or entered directly.

  • Use the arrow keys to adjust the value by one step, or Page Up and Page Down to adjust it by ten steps.
  • Use Home and End to select the minimum and maximum values.
  • Enter a value in the number field, then press Enter or select another field to apply it. Press Esc to cancel the edit.

Workshop “Super Bongo”


The “Little LUMI” appearance now also shows the hand pose for the key you press.

  • Q, W, E, R, A, S, D, F and Space each have their own matching pose.
  • Update both the main app and the “Super Bongo” mod to use this improvement.

■ Bug Fixes

  • Fixed LUMI repeatedly making small hops in place after landing on a window's top edge where it was obscured by another window.
  • Fixed conversations between LUMI characters playing together stopping after the first line when using a “Voice pack”.
  • Fixed settings rows changing height and the view shifting while adjusting the volume.
  • Fixed Bongo LUMI reacting as if a keyboard key had been pressed when moving the mouse or pushing it against the edge of the screen.
  • Fixed extra keyboard-typing animations appearing on Bongo LUMI after using the mouse wheel or buttons.
  • Fixed some key presses not being displayed in “Super Bongo” while the mouse was moving.
  • Fixed manually entered screen sizes in “Broadcast mode” failing to apply from the second change onward when applied repeatedly.
  • Fixed a manually entered background color in “Broadcast mode” reverting to the previous color after restarting the app.
  • Fixed numbers being cut off or sliders shifting in integer mod settings when the number of digits or the sign changed.
  • Fixed being unable to retry a Workshop upload after it failed to start.
  • Fixed some plugin functions remaining active or interfering with other plugins being cleaned up after a plugin failed to start.
  • Other tooltip and wording fixes.
