Played a little bit more today. Ended after fighting Popokarimu at the end of chapter 2-2. Again, this wasn't that hard of a fight once I figured out what I needed to do. At first, I thought I just had to lay down the mines and have it crawl over them. It wasn't until after I used all of the mines that I figured out the boss had a weak spot I needed to shoot. So I restarted, and when it crawled over one of the mines, I quickly ran up to it and unloaded a machine gun clip into it. Only hard part today was on the cliff because of the majini who insisted on throwing explosives at me. But it was a good day since I walked away with a few extra achievements that I happened to get.
