UPDATE: so I noticed some of my troops were in the level of the enemies, and had killed some of them. I dropped myself into the ocean (which I'd done before and I just drowned) but this time I appeared in their "floor". My 1 man who was still alive was paralysed, so I had to kill them on my own, but the enemy did not move, I had to go to where they were, and then they raised their swords, but if I stepped back they just stayed there. Finally, I won and I could move on, where I was sailing again in the sea again, but everything had a weird look, it was black and with a texture that looked like if the land was made of CD's. it has happened me before and I know that when that happens I cannot save. I couldn't save so it was worthless. Please help!!
