Thanks this is really great feedback.
I'm happy the hostage part worked ok.
Right now the end goal is to reach the tug boat (the one with lights on it behind the big wrecked ship.) Maybe it needs an objective marker.
That platforming section only makes sense if you know that you can shoot down the crates by firing at the hooks that hold them, and there's no tutorial for that yet. I didn't think that jump was possible either so that's impressive! (You can shoot a crate down, jump on it and RECLOCK to ride it back up.)
What this game really needs is a great level designer.
I considered limiting ammo but might be annoying if you run out? I suppose I could do unlimited pistol ammo and let you take clips from dead enemies for other weapons. Could seem illogical that they still have ammo if you take it from them and then RECLOCK though...
