The developer should add an option to donate through PayPal or something and if he get enough money, he can spend it to show a gameplay of the game on YouTube ads, it actually costs around 50 euros (at least in my country). Then, the game will have players.
It's so cool that you have a third person camera btw, and a zombie mode, AND an Admin Menu. The game pretty much looks done, even though the zombie mode is the only mode that you can play, but I don't have a problem with that.
