Goo? What is Goo? Is the game all about 'shit'?
I thought the same when I heard about this game. But when I played it, I found it tastier than anything.

World of Goo is a puzzle game with a very strong emphasis on PHYSICS by 2D boy. Design,story,art and music are by Kyle Gabler. The game is programmed and produced by Ron Carmel. Here are some reasons why you should play this game...


Concept :

This game picks some of the most simple but beautiful concepts,theories of physics.

In each stage, our target is to reach upto the escape pipe. In doing so,we encounter various phenomena in mechanics like Gravitation, Oscillations, Projectile motion, Buoyanct force exerted by liquid, Resonance, Circular motion, Archimedes' principle etc. Tackling and clearing each problem is really a fun and we get to learn a lot from it. The game is simple,small but needs brain.



Let me introduce to you some nice concepts of physics.

This is one of the initial stages in World of Goo. Two strong gates prevent Goo balls from reaching their goal. But I use round round baloons to open them and Goo balls fly high up in the sky.





The escape pipe is situated well above the ground. So goo Balls had to make a huge tower to reach their goal. It was OK at start, however as the tower grew tall, it's top started oscillating due to motion and weight of Goo balls. To prevent the tower from collapsing, I used whistle(look at the cursor) to pull Goo balls to the lower part of the tower. As a result, the mass of Goo balls got concentrated in the lower part and upper part became stable, thus allowing me to build further.
Logic:Considering damping is present, Amplitude of oscillation of pendulum depends on mass.
If mass is less,Amplitude is small. Since the mass at the top was reduced, amplitude decreased.



The escape pipe is at a height above the water surface. In order to take Goo balls there, I used the concept of Buoyanct force exerted by liquid. The yellow Goo ball took others well below the water surface and then realesed it's hold to sprang out of the water.Whoooooooosh!!!!
Logic:When a object is submerged in a fluid (completely or partially), there exits an upward force on the object that is equal to the weight of the fluid that is displaced by the object. This is what Archimedes s aid when he got old.




Goo balls were trying to dispose that 'undelete' block in the water. Their plan was to jump on that rope, swing the rope and when it comes exactly below the fire, jump through the fire to destroy the structure. However, due to some reason,they couldn't execute the plan. I helped them and the mission was accomplished. What was that mistake they have been doing? They were jumping on the rope while it was coming towards them.
Logic: Logic is simple. When a body is hit by an another body travelling in opposite direction, velocity of former decreases and if directions are same, then it increases. If Goo balls are thrown on the rope, when it is heading towards them, AMPLITUDE OF OSCILLATIONS of rope will obviously decrease. Therefore,they must be thrown,when rope is going away from them,so that bottom end of rope comes exactly below the fire.




Yooohooo! Goo balls experiencing NEWTON's gravitation. Goo balls jump into the space to reach their goal.
Logic: Everyone knows! Sir Isaac Newton was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian and one of the most influential men in human history. He proposed the law of gravitation. It states that, any two objects in universe exert gravitational force of attraction on each other.



So, You should play this masterpiece.



No wonder, this game receives the title of 'THE BEST PUZZLE GAME OF YEAR 08'.

This is a good post. Keep it up. :)

Interesting....

One of the tricks in the Gravity puzzle was the proper aiming of the Gooballs. Ofc, if you could have toyed around more with G Field, you'd do it very easily.

Nonetheless, A very good article.

As far as the last part, increasing the amplitude goes, There's another way of accomplishment. You'd notice that Adding the Good balls would also increase the Mass of the Swinging pendulum. So, using the Flute, you can lure the Goo Balls to the bottom end, and go in increasing the mass of the Bottom. After when you have added all except one ball to the tip of the swing, Project the last one very accurately and Bingo! The swing itself would touch the fire on the other end, without need of wasting efforts to project the Gooball vertically upwards.

Besides, The videos are nicely merged. Concepts are explained greatly. A nice article, I expect to see more of it.

I am still not sure about the logic applied in the 'WHISTLE' case.
