Noticed there was a new version (1.07), but not sure what the differences are (don't know where patch notes or whatever are to be found). In any event, I tried out the new version and managed to crack 2k points for the first time ever (11 out of 16 perfect deliveries).
Pro tip for players: manually switching between day and night (bound to Backspace and Enter by default) is key to getting a really big score. Day mode is easier to orient yourself where you are (easier to tell the difference between land and sea), whereas Night mode shows you exact city locations (the blobs of light), allowing for more consistent "perfect" deliveries.
Targeting is not too hard with a little practice. The package will land at the spot right at the bottom center of the screen (in default trailing camera view), just as the spot passes from view. This seems to work regardless of speed and altitude (although I have not tried to make a drop while boosting, so I make no promises there). You can also switch to overhead view to make the drop, but I find switching views tends to disorient me, so I pretty much always stay with the default view.
I kind of like the level of challenge that the game has now and am not keen to see it watered down too much. Specifically, I'm not eager to have delivery target markers on the ground, except perhaps for a tutorial mode, since the whole point of the game is to force you to memorize country and city locations if you want a high score. If the game told you exactly where to go next, you lose that challenging memorization aspect, and it just becomes a matter of following waypoints and hitting space when you fly over the marker, which is not really a challenging enough gameplay loop to hold most people's interest for more than a few minutes.
(That said, night deliveries already have markers of sorts for most cities, assuming you know the city's general location. Your target city, at least for smaller countries, will tend to be the brightest lights in that country. And when it isn't, you just make a mental note that that city was not this blob of lights but that other one over there.)
I think a better "easy mode" for the game would be to have a mode with pickups only (no deliveries), that just counts how many balloons you manage to pick up in ten minutes (or whatever). That might be a little more accessible for people who aren't already big geography buffs to get into the game and start gradually learning the countries, since you can see the balloons from so far away.
Sometimes the task list gets bugged such that ghosts of tasks you've already done are visually stacked with the current task, making them hard to read (screenshot below). I'm not positive, but it may sometimes be caused by picking up too many packages before delivering.
Minor bug: there is a country that has a different name in the "press M" globe map than it has in the list of countries to drop off to: East Timor/Timor Leste (respectively). I think both names are considered acceptable, but it would be better if the game could pick one or the other in order to not be confusing. You can see it when I am making the East Timor/Timor Leste delivery in this video from about 11:00 to 11:45 or so.
