I think this is more of a suggestion vs something keeping this in Beta.
A sample test would be nice, even though the kata is well explained.
Needs random tests

The a should have been :a.
It is now fixed.
In the first sample test:
a should :a
You will need to optimise your code. For example, what is the big O lookup time for a C# List? Are there faster implementations?
It should be made clear that the order must be different every time the function is called.
Yeah I think you're right actually, that looks better, I shall rework this kata
The second example of your description shows that positiv angles have to be rotated to the left (=> neg. to the right - a point for your description?!). So the example for 45 degree looks a little bit strange to me (even for a rotation to the right - "swapped values?"):
[[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12]]
normally should be
Or where i'm wrong? (i know what you are doing here - but is it really a rotation?)
variable "a" isn't described before calling it in the test cases
