Wow, this is another game that just has a certain point where I can not beat it at all. I thought at first that I lost health by going in the water. I now realize that was just the sound I was making with my weapon. The hard part is on level 1-2 (I think?) where there's a waterfall next to a wall. I don't think you can latch onto it quick enough. The bats were freaking murder.
It was cool to have different weapons. However, at the same time, it was kind of obnoxious, as I had to aim everything correctly. The graphcs are good, though. If you have a lot of patience, check this thing out! It's a doozy!
