The first time you play, without any tutorial, it is not so clear that the plane is following the crosshair; for me, that would be the place I would shoot by clicking with the left mouse button; it took a while to understand how to move the plane.
I found a minor bug, unlocking the dynamite after the anvil didn't start shooting dynamites.
I think this could attract a good audience if you would be interested in developing it further to make it a commercial project. Let me know what you think :)
