Interesting game concept and pretty fun to play.
I like the bouncing bullets mechanic as it adds a reason to be careful while shooting and not just spam the gun. I also really like the page for the game itself, it looks really good aesthetically.
The sound effects are good but they are also a bit loud.
Visually it's very simple but I think that's a good thing, the art style works quite well.
Good game and pretty fun to play. Great job and keep up the good work.
