Is there a second level or did it crash on me? I was excited to shoot a plane with a machine gun.
Between the music and classic gameplay it's clear the style you're going for and it's pretty spot on. Maybe recolor the bullets since yellow over sand is pretty easy to miss, and boy if you decide to speed run past everything the growling sounds stack up and get ear grinding. But learning game maker to make this? Great job! It's a game!
