Nice Game ! Smart take on the theme.
Few feedbacks:
The contoller mapping felt counter intuitive I kept pressing South to jump and west to grap (which are kinda standard jump and action buttons) so I ended up restarting levels instead of grabing stuff ^^.
The repeated jump when you keep the jump pressed felt a bit weird. maybe make it so you have to release the button before you jump again.
I got stuck on level 4 because I expected a key to drop when pressing the buttons instead of the buttons actually being the key. (plus you're not reusing this mechanism in the next levels, it's too bad, it could have lead to interesting puzzles)
Encountered a few minor collision bugs (mostly near breakable doors) but nothing game breaking.
Also for some reason the sounds & music stoped after a while (don't know what triggered it though)
Apart from that, The puzzles are pretty clever and just hard enought to make you scratch your head a bit without being too frustrating. kuddos on that.
Good work. I had fun playing. :)
