This was a really fun game! The game design concepts here are really solid! The controls felt a little funky for controling the plane with the mouse but it wasn't that big of a deal. I was still able to play the game mostly fine! And then there were some towns that would spawn on the very edge of the map and if I tried to fly over them I'd go to the next scene.
The thing I was most impressed with was how inticing you made the upgrades! That's one of the biggest things about these kinds of games and you seemed to really make me want those new planes and bombs!! That's really good design.
Great job on this game! Keep up the good work!
