I'm glad I managed to fix my keyboard input lag to play this, because it was pretty fun. I like the way the arm retracts after retrieving the item (although it got stuck in the middle of some walls once, which was quite funny).

One improvement I'd like to see, especially on the last level, is to not have the grabber start straight away — being able to press space or something to start moving would have been great!

Good job on this :)

Sadly you gotta restart the game everytime you lose as well, the game is pretty fun though and I like the mechanics

The only thing I would change, apart from fixing the collision bug, is the level design- took me a while to figure out that I can just grab/hide away from the first guard on level 4, seeing that I used the blocking method mainly on the third level. These mechanics would be great when explained separately.

Also a map preview before the level starts would have saved me so many restarts, but I understand there wasn't much time to add that feature. Well done game nonetheless
