A friend of mine posted this video about a game called: Crayon Physics Deluxe. I took a peek on it, and fell in love at the first sight. Crayon Physics Deluxe is a puzzle game where we have to solve a problem (mostly to guide a ball to a star) using physics rules, kind of remind me of the old-nice Incredible Machine which I played a long time ago. However, the difference (and the most interesting part) is that Crayon Physics Deluxe allows the user to create objects freely using a "pen" and transforms them into world objects which automatically follow the physics rule. Take a look at this cool video on their website:
It looks like a very nice game, but I'm not a type of guy who's willing to buy something just because it looks nice :) I tried to get more information and trial version of the game which eventually leads me into an another game called Zany Doodle, which luckily offers a trial version of the game. I tried the game and enjoyed it very much even though I only use a normal mouse instead of a touchscreen (which I believe will increase the game experience heavily). Moreover, I found out that the Crayon Physics Deluxe is actually originated from the free game Crayon Physics which is developed by the same person. However, the free Crayon Physics is nowhere as good as its paid counterpart, not even better than the free trial of Zany Doodle since it cannot create objects like a triangle or just a random line.
Should I say anything more? Just download the Crayon Physics here and the free trial of Zany Doodle here. Enjoy!
