Really cool game! The music genre-switch are a bit disorienting at first but it's a neat touch that shows the different personality of each customer. I wish there were more than 3 upgrade slots! would've bought a lot more stuff then. There's also some upgrades that are grayed out which I wasn't sure what they do (were they the upgrades for the next round?). Also in the leaderboards screen if you type "p" it opens up the pause screen. Beyond that a pretty great rhythm game, enjoyed it a bunch! the art is cute too.
