This game was a lot of fun to play! The art is well done and the sounds really fit the haunting atmosphere. The farming mechanic feels balanced with the shooting, neither feels like it's the "main" aspect of the game.
The moving and shooting were very fluid and I loved the shotgun's kickback -- not enough games highlight how powerful those things are! The hook mechanic was a little hit-or-miss for me though. Only being able to hook onto objects made it very limiting, and when I could utilize it, it did it didn't seem to get me anywhere *that* much faster. A "sprint" feature would have worked better, but then I guess you wouldn't have the "chain" thing.
One other minor issue I had was that there didn't seem to be any real reason to protect more than one patch. Just hanging around one corner (or even one side) made the game much easier with no real penalty.
Despite these minor gripes, this was one of the games I spent the most time with and it was a blast to play. Well done!
