Love this! Had a bit of a "???" moment when I first played having no idea what a mineshionshing was, but after the first two went by I realized what I was supposed to be doingg. Really delightful idea and the art + music really added to the charm and atmosphere of it.
I will say though that while for the most part I felt like I always got at least one chance to learn what an item was before I was expected to be able to filter for it, there was once when a brand new item I let through lost me a life, perhaps because I was contraband? Maybe the speech bubble from the left actually did prompt me about it and I just missed it. EDIT: Just tried it again to be sure and nevermind, I'm pretty sure that was just me missing the prompt the first time round. This was still entertaining to play again, I'd love to see it expanded on!
