I'm not really sure how I feel about this game. After the honeymoon phase of it having three of my favorite vidya characters (Umihara Kawse, Cotton, AND Curly Brace)... eh. While I could actually see Umihara Kawase working in a quest-based format, there is a lot I think this game does right in that regard, but there's a lot of rather annoying issues with that too. And this game doesn't really take advantage of that format well. Part of it might be because I'm no UK master, but it's really frustrating having to go to and from quest points, and while the save points help, it's really a band-aid on a gaping wound. So I often unintentionally backtrack when I get knockback damage or whatever. It's saying something that I used Cotton often not simply because I love her and her games, but because she made a lot of missions easier with her flight ability + whatever buffs you get from eating food. But again, that doesn't solve everything. There are more than a few missions that are still frustrating and/or really difficult even with those handicaps. Thank god you have the option to unlock her pretty quickly from the start. It's almost as if the devs knew it's a rather frustrating game. And of course, the hunger meter. This is a terrible design choice in a game like this in general. Not only does it add stress on me to get a mission done as quicker as possible, but it can lead to situations where you can just die for no reason if you don't have the items at hand to make food. I still like the game (but not nearly as much when I first started playing it), and I still think it's an interesting take on the UK games, but I really do see why it gets a lot of flack now after playing it rather extensively. Can't speak for physics and whatnot since I'm not really trained on that area, and some of that is subjective from what I've seen, but I think I know enough to see a lot of the game's issues.
