Was kind of fun for ~5-10 minutes, but yeah.. definitely huge potential to be a fun little gamified way of learning the current world. Hoping that the country names would be shown in a fun way in a future update. Maybe instead like it shows the name of the country under the plane in your video, could also have an option to have a map variant where all the country names are written over them - bigger the country bigger the font (or just have the country name appear when flying over like revealing it from a 'fog of war') and maybe even add other info for those countries too (nationality, flag, capitol name, etc. in the corner of the screen somehow).
Gameplay wise it would be good idea to have an option for a compass (something that leads you to the 'target', even if it wouldn't show directly but just '# meters away' as you try search for it.) I like the idea for speeding up, so maybe for accurate 'package bombing' could have a key (CTRL) to slow the plane down and make a little dot on the map where the package will land. To keep people engaged more, could have a scoring system of some sort, or just plain old upgrades (see what I did here har-har) so perfect deliveries unlock plane types/colors/trails and such.
Personally I didn't like the nighttime orange city lights (and them matching country borders) but its a good idea to show population spots somehow like that. Maybe some option to set the time as you fly (having sun always be positioned static with the plane - morning/noon/evening/night)? Also could have an option in the menu that keeps the world 'real-time' using system clock. World height-map is a little too funky and needs to be toned down, as it makes some tiny islands be just spikes, and sudden elevation of mountainous areas does not feel natural at all (I'd honestly be more comfortable with the world being much more flat once the clouds get added in).
Game run fine for me without any complications (beefy specs, so no idea how it would be on low-end system). Needs many more options (resolution/keybind change to begin with), some sound (plane engine rattle / chill background music loop) and a proper UI (both menus and in-game). Otherwise I wish this project all the best and hopefully it will shape out to be a fun little game in the future. Would definitely buy it again for a proper price once it gets fledged out, and preferably a Steam release for a future handheld experience ;)
