This game is so twisted and sadistic... and so much fun!
I really like the idea and concept and you definitely pulled the core mechanics off here! It feels so good to aim, place the crosshair, and then "pull the trigger"! I do not know how you got that gun sound, but it is very good for a lofi sound. The only thing missing is pulling the slide and loading another bullet in each time.
Would be really cool to see this one expanded out a bit and either add some sort of timer, or a panda kill count for advancing on. Even adding some upgrades or something too possibly and different level layouts, etc.
Nice job!
