Really fun concept and cool artstyle to go with it.
It took me a bit of time to understand what losing items and losing clients did at the start, a quick "help" panel explaining mechanics in more detail can easily fix that. Some item sprites were a bit too complex to really understand what the item was (mainly thinking of the big red armor) and it took me more time to get which item item category they were part of. It is a bit frustrating to see clients ask stuff you don't have and the game won't give you at times, maybe showing what the next client will want (in addition to showing the current client) would help to plan better.
But really cool stuff overall, love the drawings.
