I really dig the presentation! The reload animation, the use of bloom, and the way the hands are animated is all really nice!
I would like to maybe see a more clear indication that you can hit the slot machines. The sound/feedback when hitting a ghost could also stand to be a bit punchier maybe. It would also be nice to be able to choose which die you throw from your hand, rather than just throwing the next one.
All things considered though, this game has lots of style and polish, and is a great interpretation of the theme. I'd love to see what this could turn into if fleshed out more :-)
