I created a pair of post offices, staffed them, bought them vehicles and a few amenities, set routes and fixed prices. All of that took roughly ten minutes. I spent the next 50 minutes doing other things in real life. I cooked some soup, put together a decent sandwich (it even had some lemon zest in it), made a banana split, went to the bathroom, and got some things from my car that I'd forgotten earlier in the day. The whole time, the game was at 3x speed. I occasionally hit "ok" on the dialog that told me the day was over, but most of my time was afk.
I came back to the game and found that after a week, nothing interesting had happened. My operation flowed smoothly and made me a good return. Given a month I could open another office, given a year and I could probably edge out my competition with decent advertisements and expanded service.
Here's the thing - the game played itself. All i did was set it up. There's no management, the prices were already reasonable, there were never any problems, and I didn't have to do anything. Other tycoon games give you a reason to keep playing - more things to build, more people to attract, more stuff to see. This one doesn't - it's over as soon as you've finished setting it up. It's barren and simple. It's so simple that I can't recommend it, because you won't get anything out of it, unless you're looking for a screensaver that doesn't move, but takes ten minutes to set up.
Glancing over the developer's history, it seems clear that this is common. Produce a bargain bin game that's very simplistic, release a new one every couple months. And hey, they apparently make enough money to stay afloat, so cheers to that. Given how many games I play that were made by people who tried 10x as hard and came out roughly equal to this one, I can't really decry someone who is literally in business making this sort of thing.
