First Aid Kit
If you have any technical problems with the game, here are a few things to do:

Check ingame log
Press F9 if anything goes wrong to toggle the console and include the error shown there in your bug report.

Launch with logging
If the console doesn't show any errors, try launching the game with the --enable-logging flag: You can start the game with the flag by opening a terminal in your install folder (shift+right click, open terminal here) and then entering "Core Defense.exe" --enable-logging

Black screen?
Others fixed this issue by launching the game with the flag --disable-gpu-vsync, see above how you launch the game with a flag.

Grey screen?
Sometimes it makes sense to check for a corrupt profile. Go to

%APPDATA% on Windows
~/.config on Linux
~/Library/Application Support on macOS

Find the folder "core-defense" and delete it or move it somewhere else.

I get a gray screen. I have tried deleting profile. Uninstall / Reinstall.

@rothhfusz: can you try running the game with logging enabled as described above and post the output? What OS are you on?
