Cool to see some 3d projects! I was not totally sure what I was supposed to be shooting since the drones are small. It would also be cool if there was some effects from the gunfire.
Web version is missing various graphic features; gun effects are available in the stand alone version but I noticed just now the downloads were set as hidden. I've fixed it: now you should be able to download the stand alone Windows, Linux and MacOS version as well.
