Fun concept and nice environment to traverse! I think a little ocean-y or pirate-y soundtrack would have fit right in.
It was a challenge to keep the chests from getting caught on corners, and it really made me wish ships had a reverse. The upgrades (as advertised) made the deliveries much more manageable (it's so hard to turn lol). Also very glad there was a compass to help tell which direction I needed to go! I would have been very lost without it.
