I will have to upgrade to a new engine version, so I will likely update the desktop versions too.
What kind of hardware do you have? And can you send me the contents of game log from /home/<user>/.local/share/polychoron/logs/godot.log?
That integrated GPU is HD Graphics 500 which is unfortunately not going to run the game very well out of the box. You can lower the in-game graphics settings if you haven't already done that.
One another thing that might help is running the game with following command line argument:
--video-driver GLES2
It will look worse but should run a bit better on low-end hardware.
