Little Error - Recent Files

For a "Project" menu item, the "Open" button causes an error if the previously opened file has been deleted.

Try this:

1. Open any project.
2. Delete the project file.
3. Click on the "Open" button.

I checked it from the "Modules" menu - there is no error.

Thanks for reporting this to us.

I will forward it to the programmer. Please wait for the news.

Thank you so much. As you go through the stages, you will come across numerous obstacles that may cause your cube to crash. Spikes, moving platforms, and other obstacles need exact time to avoid. The difficulty geometry dash subzero grows as you move through the stages, making it harder to keep up with the rhythm and time. While Subzero does not feature comprehensive checkpoint systems, there are places in the levels when you can get a better sense of where the hardest areas are. Take note of these areas and concentrate on them until you are confident in your ability to pass them.
