So, I played the game in its entirety. Here's my review:
THEME: 4 stars. Chain was definitely present, but destruction was a bit lacking
FUN: 4 stars. It was definitely fun, but could have been better. Swinging with the chain is hard but satisfying, but you don't get much chance to do that! Plus, the chain doesn't feel so much like a chain than an elastic, which is OK, I understand how hard it is to make a chain with good mechanics, but I would have prefered to have a chain that collides with the walls, still.
CONTROLS: 4 stars, they're intuitive and there. Maybe reassigning them would've been good.
GRAPHICS: Beautiful graphics, 5 stars. Just found the animation a bit lacking
AUDIO: 4 stars. Music is good, but sound effects don't fit
ORIGINALITY: 4 stars. A basic mechanic, that comes pretty fast, but well extended
TOTAL: 4 stars
