It is a mix of retro and io stilled game made using Godot engine. You are a connon turtle moving with a and d or arrow keys. Press space or "enter key" to shoot. Try to hit all the characters falling with your gun. Try touching the yellow upgrade falling object to upgrade your gun. It will also auto- upgrade as you progress thru harder and harder levels. Can you get to level 6?  Enjoy this very addictive game.
