I'm glad you liked it.

Yeah I thought the shop owners reactions were very believable. I think that many people would react similarly in that sort of situation.

I like your interpretation of the ending as well. I think thats its probably more fitting than GUI or psychogenic death (that must be its proper name). Psychogenic death probably doesnt quite fit the situation but thats where my mind went. A complete disconnect from reality makes more sense.

Thanks for the discussion :)
