Currently, the game is quite small.
Despite this, it's actually really fun!
The art is really cool (seriously, good job with that hand) and the music is a bop.
As for criticism/ideas:
Maybe you could add art of the actual people who you're robbing, as well as all of your other ideas? It would also be good to have an indication of your lives, so you can see when you're going to die, and this could tie in with the art of the people.
Maybe also moving the part that you have to hit, so that it aligns with other parts of the song? That could be interesting, and also throw people off a bit.
Oh and it would be cool for there to be a bit of a time limit/punishment for sitting around too long, so you can't just win every stage and get all of the money too easily.
Lastly, there's a bug where sometimes I click it as a miss but it shows "OK" instead. Just thought you should know that.
Anyways, have a good one, and I hope that you keep working on this game after the jam's over! It has potential, I think, and I'd definitely come back to play it if it were expanded a little.
