Cut It
Back in the day, physics based gamea were sparse and hardly available. However, today, it's almost everywhere and there are tons of physics based games that are fun to play. Take for instance, Cut It. It comes from the same makers of Crayon Physics and utilizes the same physics based principle as the latter.
The only difference is that you use scissors to cut up blocks and get the white box to hit the green platform. Definitely a fun and intriguing small game.
