Graphically, the most impressive game I've come across so far. The game is simple yet serviceable. I think the theme and limitation are implemented well. To see (hear) voice acting as well, was a great touch.
Art style was cute and I absolutely love the mix of 2D and 3D assets. I like how you have to carefully pick your route - not all routes leading to the side where the customer resides will lead to the customer - so there is a bit of memorization/puzzle aspect. Animations, yet simple, are smooth and work in conjunction with the overall paper-mario-esque aesthetic.
Overall, I didn't encounter many bugs at all - so I can tell that the programming side of things was handled pretty well.
Great work! (bonus points for using an accordion in the instrument arrangement for the music).
