Definitely a tough game!
I was having a hard time getting the blocks moved out of the way in time not to mess up the structure I was creating. I was only able to pass 1 section (got 360 points). Once I realized the shape didn't need to be perfectly filled that helped but still had a hard time getting things moves in time.
The idea was cool, the style was neat and really creative, I loved the error block lmao. Overall I think with a little tuning this could be a super fun game. Please check out and rate my game if you can!
