Hello! I played your game using a Vive headset and Index controllers.
I don't play a lot of VR shooters, so... Maybe I just suck at aiming, but it was very hard to shoot the bad guys, so, I died.. a lot. And didn't make it very far at all. I also struggling with reloading, I wasn't able to do it nearly as smoothly as you did in your game play video, but I was able to reload - so nice work on that mechanic!
I believe you tried to fit the theme by shooting people below (ground level) and above (rooftops), which is a decent take on it!
Overall, for how long we had to make these games - nice work!
