This seems like a really well-polished topdown shooter. I really liked the level system, it's a shame that there weren't more levels. I liked how complete the 'opposite' theming was. It used the opposite of so many tropes, but in fun ways. It never went too far as to be annoying (it didn't swap 'confirm' and 'deny', for example). I just wish that the healthbar turned from red to green from left to right, instead of from red to orange from right to left.
