There are so many great physics style games which require you to draw objects and let gravity do the rest. Physics Drop is a bit more basic than some, it doesn't have flashy animations and a high production value. It is just very simple lines. There are over 100 levels, and I'm not sure we know exactly how many yet. The game gets 4 stars, there are some complaints about it being difficult to control on some devices but I don't think it affects most users. Also note that the levels aren't very well numbered when you play through so you may need to look at a few of our videos below.
