Hi Fritz,
I can't say I'm particularly skilled at literary analysis, but I enjoy it nonetheless. I think it's arguably just as important as artistic critique, maybe even moreso given my thoughts on the value of technical skill vs narrative deft and heart in my own work.
Anyway! Let me give you my thoughts on your comic thus far, and then I'll link mine for giggles.
I feel like you've said your influences before so maybe I'm biased, but I do see an existential and sort of nihilistic kind of.. flavour to your work, which is played in a -- it's kind of like that quote attributed to Yeats, that's like:
"Being Irish, he had an abiding sense of tragedy, which sustained him through temporary periods of joy."
Decaf and to an extent Sprudelwasser as well seem to be snapshots of those temporary periods of joy. It feels like there's a greater realm of, not necessarily tragedy but a kind of sobriety around the world and story they inhabit in Decaf. Like a gut feeling of dread. Like news you never wanted to hear. The moment before you catch on to how bad it really is. Not hope, but disbelief. And it seems like the purpose in the universe of Decaf at least is not one of cosmic sanction but one of pure happenstance. Things happened this way because of the conglomeration of wills clashing and interacting, like how meds that you shouldn't take together interact - creating new outcomes totally separate from the individual trajectories of each will.
I don't have much real literary comparison, and maybe I missed the whole idea of this thread. I'm at work so I'll go over the comic again later and see if I have any new thoughts after I get home, but yeah. I will link my comic, Intergalactic Hockey League, here, if anyone wishes to analyze it, despite a lack of any overt literary reference:
