You need to try "I spent last week dismantling the mob (but enough about me, how was your weekend)"! I had a bit more time to develop that one, and if you enjoyed "it's not like the amulet..." this will be right up your alley!
If you like fast paced fps you can check out give-me-back-my-glasses-collection .
Now, if more slow paced and deliberate shooters are your game, you can check out my first jam game ever "While you sleep, I hunt ghost's with the pope's revolverWhile you sleep, I hunt ghost's with the pope's revolver". This one's doesn't work in browser, but I think has an original premise.
