It was cool that you implemented a story in the game that's pretty cool. I'm not a big fan of tank controls in general I think it's very hard to control. but I did eventually get up to the 0th floor and there were just soo many enemies I wasn't able to get all the way through. But it was very cool. Also, I'm unsure where the bullet or raycast was starting from because there were a couple times when I thought that I should've been hitting an enemy but it just wasn't.
But still a cool solo project to go through.
