This is probably one of my favorite games so far!
I was mildly unenthusiastic when I saw the concept, because it felt fairly standard as to what one would expect from the theme of "delivery" - and that's true, the concept's nothing special. But the execution is great!
The difficulty is exactly where it needs to be - I never got a game over, but I always felt a little bit of pressure that failure was imminent. When that pressure arrived, a wry player could spot the occasional shortcut - ways to hop over fences, cute detours, ramps - which are oftentimes just useful enough to be worth noticing.
The music's good, the gameplay's good, you play as a disembodied, driverless motorcycle - great work, developer.
