Very cool bullet types, and a very hard game for me even when trying to use the buildings as cover. Some tips, in case you continue to develop it: make buildings stand out more (visually), make the game over screen visible for longer, and upload a zip rather than 7z because more people understand it. I used Godot to run your PCK file on Linux, so if you would do a Linux export then it would also work. P.S. Nice debug output on the console.
