This is basically a parkour style platform game in a relatively small but open area where you are tasked with delivering things, but at any point in the game you are always losing energy that you must maintain at all times whether you are currently on a delivery or not.
The energy mechanic made things pretty interesting because it gives the game a sense of constant urgency. You need to make deliveries because regaining energy has a cost and you get money from deliveries (there's also some money collectibles in the world that can help though). You only get the payment at the end of a set of deliveries so as the number of deliveries you need to do increases in number, the need to complete the objective as fast as possible becomes greater.
What makes this work so well is that as you do more deliveries, you also get more and more familiar with the paths within the little open world, so your traversal skills goes up with the difficulty.
While enjoyable, it does get repetitive at some point though, as the deliveries always feel the same overall. There are upgrades to get, but they are pretty easy to get early game, so nothing really changes for most of the game. The world is built of sections connected with pretty boring hallways, and you'll have to constantly go through them (I assume this was to help hide parts of the world loading). There are also collectibles on the side to collect, but given the game doesn't track them, it's kind of hard to tell if you found them all or not.
Overall though, I did have fun, and while not perfect, I really liked the premise being pushed to constantly move in the small open world. The parkour mechanics and platforming also felt pretty good, which is nice since that's pretty much all you are doing the whole game.
