Dude it's really challenging to complete all the 6 boxes, but I managed after a few rage moments lol. I just wish a restart button, cause to someone who's seeking the 6 boxes there's no point in wait the entire trip if I already lost a box, I kept refreshing the page over and over. Another thing I didn't like was the lack of feedback to damage and the enemy planes being immortal. Other than that, you had a good idea with the platforms to exit the plane, I can imagine that evolving in a bigger project, congrats for that, it's cool to jump from the plane and go back to it, really satisfactory, the controls are simple to use, congrats for that as well. Visuals are cool and I liked the music. Well, congrats for your game, in summary, my 3 suggestions are: add a restart button, visual feedbacks for damage and allow the player to shoot the enemy planes.
