The best I could manage was $6.26 which is a long way off from the goal. No concert for me. :(
I had the same idea of giving exact change for my jam submission! Getting quarters at the arcade is fine, but I'm not sure what to do about getting more of the smaller coins, I ran out of pennies quicker than anything.
I didn't know kids in the 80s had five o'clock shadows at 8am :D
I like the gameplay, but the time constraints definitely feel too tough. Especially since it ticks down in menus. I did also have to fight with the camera to be able to interact with customers and shops, which wouldn't have felt too bad if it wasn't using up precious seconds.
