Really liked your plane start-up sound effects!
I think the game could be improved with some indication on what the "correct" solution to the map was besides just displaying a score. And also letting the player know what icons they were going to be working with ahead of time. It wasn't always clear to me what the actual things translated to in the drawn map form.
Kinda curious how you implemented the scoring in any case! Was it based on the faint grid on the paper? Relative positions of the icons?
Very cool seeing someone else's interpretation of the same idea :)
