I am not able to switch sideviews using the number keys? Cool concept, I would be interested in playing it more if this is fixed. Also it would be cool if a sensitivity slider was added, it seemed too high for me.
I've submitted a new build: The helicopter movement should be fixed, and while I do not have the time to implement a slider, I have after testing the game on a few different monitor sizes arrived at an overall more comfortable sensitivity level.
