I actually was kind of curious if there were more music references hidden around, as there was the Dowland graffiti, not to mention the title "Serenade." I completely missed the name references for the characters, since I don't really know much about music at all, let alone brands or types of instruments.
I get what you mean about ambiguity on enemies' fates, and I appreciate that it's not just a concrete "kills everybody or nobody" dynamic. Aaaand because I'm deranged, when you said "more cartoony killing," I envisioned Mezz replacing one of Mahir's cigarettes with a stick of dynamite.
