Hey, you did a decent job - but I think there's some things you could work on.
One is that I believe you should try to make the grappling hook more dynamic. Another is probably make the reticle a little bigger, it's a bit too small. Make it so that you won't get one hit killed from being touched by the enemies, also make it so that it's possible to see your health & ammo. It looks nice, although I believe you took it from assets? The music was good too, was that from an asset too? If so I think that you should try to challenge yourself and make your own. Overall you did a decent job, I hoped you learned more!
