Fantastic use of the 20 theme. Only really 2 criticisms I can make, the objective for the game doesn't feel like it's fully tutorialised. At first I was just nuking literally everyone I could see hahah(but then I made sense of what I was meant to do in the 2nd playthrough)! 2nd criticism is on the controls feeling a bit difficult to use, it might've worked better using the scroll wheel for example(though I think the controls being difficult might add to the tension haha)?
Overall, I thought this was a pretty fun game to play!
