Thanks for playing the game! I see why you would be frustrated at the dice spawning because after I tested the game, I realized it was very slow, but it was too late to upload again. I also should have thought about the rotation as a lot of people I know are used to using right click for rotation. I think a good alternative maybe have been changing rotation to right click and making it so that you can switch between destroy/build modes and do it with left click. I did actually have a version with the UI finished, nicer looking graphics, and faster gameplay (Dice and delivery locations spawning in faster), but I was unfortunately a few minutes too late uploading that version.
