Really cool entry, really charming. I loved the audio especially.
I think it might have been nice if there were some more hints or pointers considering its a game jam, because i did feel sort of lost at some point. Maybe i just picked the wrong flight destinations and got unlucky. That said, i think this wouldn't be as big of a problem in a non-jam situation as i could spend more time with it.
I also like that you can toggle the shader. I think it adds to the feel but its nice having the option, same with the skippable intro.
