I think that it's ironic that five years ago this would have been considered the very best possible thumbnail you possibly could have made for a video game of this type. Well maybe. It does sort of represent it as being much more visually compelling than the actual in-game experience.
As for the actual game I think you've implemented it pretty well. The real-time rotation is a nice twist I haven't seen in the genre before and I especially appreciate that you give us the CCW and CW options just by letting us choose whichever set of keys that we want. The one quality of life change that I think would really improve things is that doesn't seem to be a way to come back to where you left off, IE a level select / continue option.
