That music! So good!
From the moment you open the game being greeted by that wonderful bop! It really suits the game well. I really love the way you handled the grapple mechanic, adding in pulling as default and rotate on the various space orb things.
No real criticism from me other than that there are a few bugs pertaining to the UI and as others have said being able to do things when already dead. Frankly neither took away from the experience whatsoever.
All in all great job chief! :D
