Funny experience :) I feel offended at your Barbie Girl comment from our game having maybe only 7 references to it. At first I was upset because the narrative felt more like an informative, but then you gave me lasers. Thanks for the lasers. Unfortunately it seems I encountered some kinda bug on try 2 of hard mode and I got a game over with 30% health left :\
Oh and a little hot tip, your fullscreen is malfunctioning because your Unity project and itch.io both have full screen buttons. You could fix this by through your itch.io page by unmarking the fullscreen button extending your Height by 50-100 px under viewport dimensions
