Finished all 4 levels, unfortunately those bugs mentioned on the page made it a bit tricky but not too complicated.
I liked attaching to enemies and the physics interaction. Also movement is nice.
Game play wise i think it's a bit shallow, it could be expanded by adding different attacks / combo or special moves or new mechanics similar to the grappling hook.
Graphic is very nice, maybe it could be a bit flashier during attacks or other actions by using more particles.
Audio effects are missing, but the music is fitting for the game setting.
I would have liked an endless mode with high score. Bonus point for the story though!
