I was actually pleasantly surprised by this. The game looks pretty good actually, and the music is also way better than I was expecting ngl, it is deserved of having it's own downloadable after all.
I also really do love this control scheme, it feels quite smooth and simulates a plane control really well imo, and it feels awesome to precisely squeeze into bullet gaps with that, and when I died trying to do so it did always felt like it was the fault of my own stupidity so that's always nice :>
Other than that I don't really have much else to say about the game, it do feel pretty simple still, but hey, no problem with that.

On a more unrelated side-note tho, I Love how you went completely overboard with the story xD
I can tell you were really having a lot of fun with this, and honestly, you got me hooked, I was fully invested on it. Next time try using another background for the game page tho, or at least a better font color, because it was kinda hard to read it as it is now, but this already have nothing to do with the game itself anyway x3

This was fun, presentation is nice, controlling such plane against aliens sure is a cool setting, I like the music and flying feels good as long as you're in fast mode, the simulation movement makes for a nice change of pace compared with other entries. Good job.

I see a lot of potential for a top down plan game like this. The look and sound was great and it was fun hunting down the flying saucers.

Really cool explosions ! The gameplay works pretty well, maybe enemies lack a bit of range, I found it easy to just stay out of their reach and shoot them while they are not on screen, which made it quite less fun than dodging bullets . 

Overall, it was quite fun ! The level is quite long, but not too much so it did not feel repetitive, and it was the right level of difficulty for me, I finished it with zero lives left.

Really cool concept !

I dig the theme of fending off an alien invasion with WW1 era but more style biplanes ^^

The models also look really good, and i like the abundance of effecs for impacts and not to mention these fancy Explosions :O

Controls are pretty smooth as well, and the mouse aiming made it for just spot on precision for both shooting and navigationg through bullet patterns.

Music is also quite cool !

Overall solid entry, great job :)
