Luminous's Spectral Light

I'm fairly sure Sommersault only uses 90 degree rotations.

This is vertically symmetric so it only has to cover 0 through 45 degrees and the rest can be handled by 90 degree rotations + mirrors - 5 different animations would give 32 angles, 6 would give 40, etc. with +8 for each new drawing. From what I can see in the video, they'd only need maybe 64 total angles to do it without rotating anything other than 90 degrees.

Then again it's not pixel art, so rotating intermediate angles wouldn't look ridiculous like it would with normal equipment.
