The graphics looks amazing, the sound plus the clock shatter effect is really cool!
The black tutorial environment feels pretty special and new!
One thing that I didn't like was that the weight blocks' physics are a bit slippery and I couldn't get them all on the weight. Also I accidentally dropped one of the hints and it became pretty difficult for me to view it as the clock didn't reset it for some reason.
But overall, this is one the most polished game here! It's insane how much you did in such a short time frame
