Ok so this idea is great and plays well but the camera is the worst enemy.
Sometimes hard to see what is going on as so much is on screen and the slow effect sometimes is annoying. However I do like the idea and have a few suggestions.(My thoughts on the game)
-Put a number above players head for bullet count.
-Darken the background a little so the bullets are more noticeable.
-Player outline to make it easier to see.
The work you did is great and this could make a fun game with more time 👍
