Wow I'm really impressed with the wall crawling ability you've made, it's really impressive! The cut scene at the beginning was awesome as well. First time I've seen someone try that around this skill level! Also the music was a nice little touch up
That being said though, there were some issues.
Switching from surface to surface was a bit glitch-y and it made getting to the turrets difficult. The bullets going through the wall made it so you could never find cover from the turrets and never had a chance to not lose health. It also wasn't very obvious how to shoot to start out with. That took me a minute to figure out.
I hope to see more from you though! This was really cool!
