Really fun experience! I really liked how I could move quickly and just keep getting shots off, and the placements of furniture and such to sometimes block an enemy was clever too! I also liked the idea of civilians who you must avoid to add to the quick reaction time gameplay. I was a little slow and somehow didn't understand you needed to land your shots or else you must reload, some reason I thought you had 2 bullets before needing to reload lol. It's definitely my fault, but what could help overall is also having some UI to show whether the gun has a bullet ready or not.
Otherwise, a really solid and fun game! I also enjoyed the presentation and the elevator buttons acting as "levels" was a really nice touch! Great job!
