[Decompilation] [th01] Sariel: Pattern 11/16
The one where Sariel fires four semicircle spreads from their shield, 10 frames apart. So nice and simple that it warrants trying out a more compact coding style for these `for` loops with two loop variables. The more I look at it, the more I like it? I do think it's good. Completes P0178, funded by Ember2528.
