I played all modes. Random was surprisingly easy (got close to 3k at least). Rectangles are probably the easiest.
The thing with Corners is they can suddenly just fly out unlike other modes.
I also had a bug when playing on Random where the coloured circles were on top of the ranking (I was not able to see the numbers on the left side).
I only played online. I might record a video at some point testing the stand alone build on linux with wine.
I am gonna test the linux build.
