I give this game a solid three stars. I do so because of these reasons:
-The characters that you can talk to have no purpose, so why have them there in the first place? Make them say useful things sometimes. Not all, but some.
-Instructions not clear. It gave me the basics, but on the second level where you come across the floating heads, it seems impossible. I passed it by playing around. I discovered that you can actually kill them when you hit them with the hook, only from underneath. This wasn't mentioned, and I am sure people will not pass that level without knowing.

But other than that,the game kind of gets too difficult, and some of the levels are nearly impossible. Keep up the great work though!

Not bad, controls a bit a weird. What did you make this in?

This is a solid 3 for me. Great concept, and art that fits (but could be better).
What beings my review down is the controls. Up to talk, up to go through doors, and up to shoot your head vertically. Space should be interact, or maybe down.
The character is also very slippery, instantly reaching max speed and sliding to a stop (or so it feels). You also can't swing using your hook-head. If you hold up, it should keep you against the ceiling. Pressing down while still holding up should lower you, so you could swing back and forth.

But, good game nontheless.

"You got around that really good. Will you wipe my bum for me?" What the hell? That "joke" wasn't even funny. This game isn't good. It is cleaver. That's what the one half star is for. It is unpleasant to play. The music is repetitive and annoying, with that tiny gap that lets you know the loop started again. The gameplay is based on a clever idea that was very poorly executed. I liked that the tilt of the head, in the opposite direction of movement had an effect on the trajectory. It was not a strong enough effect. The levels are ugly. I am sorry to sound harsh, but visually, the game is extremely unappealing. It is something I would not want to spend extended periods looking at. The in game instruction is insufficient. "These things will mess you up." That sentence failed to convey "If you hit them with your head a bunch of times, they die, and are out of your way!" I had to find that out myself after a number of frustrating deaths. I just had to mute the audio on my computer, because it continued to drive me mad while I wrote this, and you cannot turn off the in game music. I did not like the way it resized the game, and made me change the size of my browser window manually to compensate. Basically, this was bad. It even gave me a slight headache.

1: The game window is larger than my monitor!
2: "New Game" is not clickable, and none of the buttons on my keyboard do anything! I can not play this game.
