Very Challenging, kinda rage inducing (in the best way possible). I think the slowness is what makes the game charming, it's supposed to be slow and methodical. Would be cool to see if it's possible to implement two claws like in the thumbnail (which was what attracted me initially), and have one of them "lock" in place for more fined tuning.
This reminds me of A little to the left, which I believe was also a gmtk jam game? congratz for nailing the same feel :)
