How random
I think it might be the first submission I ever saw where the only person credited was the "actor". While I don't think these kinds of submissions belong here, this was still pretty good. At first, I thought it was going to be a parody of "Tik Tok". It was mostly because you started the song with "Wake up in the morning". The coolest part was probably when you showed the gameplay with the zombies being killed. I was actually expecting it to be more outrageous with the title.
At least it looks like everyone had fun with this. I suggest you maybe make the rhyming a little faster as you don't seem to emote that well. Now, I'm not familiar with this game, so I can not complain about if it was authentic to its style. You consistently keep up a good sense of fun. I hope you continue to kill Nazis and zombies!
