I loved this and I hated it at the same time. That's when you know you've made a good game haha! Every time I got my buttocks handed to me I just dived back in and tried again, and having replayability is a fine asset indeed =)
Seriously though, I didn't hate it at all, the whole thing looks gorgeous, plays amazingly (even better with a controller I'd imagine but I like to make my life difficult!) and the little nugget of story piqued my interest enough for me to want to see more. Keep up the excellent work, I really hope you hit your Kickstarter goal!
