We had this simple game, where you play a helicopter. It was very simple sidescrolling 2D game with only 2 colours (orange and black). You flew through a cave and there were missile turrents that only could shoot once. Your heli could shoot destroy the turrents with is own missiles. The cave got tighter and there were multiple levels. It could have been homebrew, it ran in a small window using workbench, I think.
Here's what it looked like from what I remember:
(yes it looked pretty much like this, very simple)
I don't have any high hopes of finding it, but it would be amazing if someone knows it.
