Nice work! I really liked the small touch how the music became more hectic as the clock was running out. The first level felt perhaps a bit too easy, as I got more extra time from the deliveries than it took me to get between the delivery spot, but the later levels felt more like challenge.
Also in the web build there were some unfortunate large lag spikes early in each level, when jumping for the first time and when collecting a power-up for the first time. Thankfully after that the game ran smooth for the rest of that level.
Cute main character!
