I want to like this more, but this game just has a lot that I don't like. So many levels are either boring, unmemorable, or uninteresting that I find this to be a chore to play sometimes. I'm not a fan of the new Zero Knuckle as most enemy weapons are pretty bad. I like the new ex skill system, but that's like the only positive change. The elf system is worse than 3's, only limiting you to a couple elf effects, some of which are largely the same, and the crafting system is awful. Unlike games with a proper crafting system, this game doesn't tell you the recipes of over 80% of the parts in this game. It's bad design and forces the use of a guide. I got every part in this game, and the grinding was honestly not that bad; it was kind of relaxing at times, but I also learned that a majority of the parts in this game are useless. Quick Charge, Double Jump, Rolling, and the Junk set are all you really need. If you're playing this game, look up how to get those, and you'll be fine.
