Awesome
I loved it.
It was clever and very stylistic
People who complain that it's too hard are missing the point, games like this need to be hard or they aren't fun. Learn to enjoy a challenge. I hate how games today are always so easy to cater to people who shouldn't really be playing games precisely because they don't enjoy challenges. Just because you can't finish something within the first few minutes of trying doesn't mean it's too hard, it means it wasn't designed for retards. (Most people it turns out) Seriously though, if you can't finish one particular level, leave it for a bit then come back to it. The fact that it's challenging will mean that you will have a greater sense of accomplishment when you actually do figure it out.
For anyone who doesn't know, there are more challenging sequels at:
