I like the idea of it, and you captured the experience of playing real life crane games with it struggling to grab stuff :D (not a criticism, once I got the hang of it it wasn’t too hard to pick stuff up with it!).
I wasn’t sure how to give the money to the checkout guy so I wasn’t able to get past the first level unfortunately. I tired left clicking him and throwing it at him, but if I needed to do something different then let me know and I’ll try the rest of it!
