Hi, you requested some feedback in the discord server so I took a look! I didn't see this one during the original review portion of the jam so I can't compare the current version to the original.
I see previous comments have touched on the controls and I would agree with them, for me it feels like being able to select a square by clicking the mouse makes a lot more sense than using the arrow keys. Speaking of the arrow keys, if you mash in one direction while the cube is moving it will end up switching the selected square even if shift is held down.
I don't really know a lot about Rubik's Cubes, I'm guessing that you can't move the middle column in a physical version, which is something I kept wanting to do while playing this.
I appreciate the ability to change the backgrounds and the music and the leaderboard is a great idea if you can get it working.
I hope that helps!
