I loved it!

But your animation wasn't very smooth or clear. The fight scene just looked incredibly confusing, and I had little sense of what was (physically, NOT emotionally or conceptually) going on.

Great!

Isn't that Swan Lake? Great Remix.

Great!

I didn't understand the kangaroo or the guy at the end, but the rest was awesome! Just my sense of humor.

Would be fun

but the difficulty curve is minimal. It needs to get harder faster.

Fun, minimal, BUT:

Where are the side-walls? No, really, you have to show us with a color change or something.
Some of us can take a more vertical difficulty curve than that.
8-Directional movement. You know, checking for each key-press individually, and if up AND right are being pressed, then the functions for moving up AND for moving right will both occur.

I really enjoy this style of game, but it was obscenely slow. The challenge came when I was at the top, dead-ended, having to backtrack through the maze to get to a route that wasn't blocked off. If it were faster, and the dead-ends absent, people may enjoy the game more. It's more of an analytical game at the moment, and less one of skill.

Love it. Amazing. Catchy and creative.

Very cool, I wish it were longer. I could see this in an RPG, in the right setting.

I'd love to see the picture of your theremin/celest.

Yo dawg. Look at a picture of something before you try drawing it. Then, do some practice sketches. Get the basic shapes of everything right, and fill in the details inwards from the form, not however the heck you did it.

A "cool" background doesn't make a poorly executed sketch cool. If it was an unpracticed speed sketch, maybe it didn't belong in front of the world. If you wanted to show off, I would have practiced and made sure I knew what the shapes and forms looked like before going. All you're telling the world is that you're rich enough to have Photoshop CS6, but that you're not using it for anything productive. That's sorta like diving a Ferrari in a Monster Truck Rally.
