macOS Mojave has a new feature called Dark Mode which applied an overall dark theme to OS interface. This has changed the appearance of Finder as well.
OctoMouse's app icon (OctoMouse/OctoMouse/Graphics/Icon.png) is a black mouse pattern on a transparent background, which is invisible under the Dark Mode as shown above.
Therefore I suggest that it should be changed to a white background, so that it works for both Light and Dark appearance of macOS.
This is a suggestion to improve the app icon.
