An extract from the Tiki Towers review by WiiWare World:
"Some might see this jungle themed construction game as a bit of a cash in on the success of World of Goo. After all both games command you to get from point A to point B by building a structure. However, this is where the similarities end. For starters, the structures are more conventional here and resemble traditional 'architecture' albeit in a simplified form. No wacky triangle shaped goo bridges with balloons to hold them up, just traditional girders made of bamboo that you must place into a shape of your own design with the help of your team of monkey engineers. Their job is to carry out your orders by placing bamboo pieces, stabilizing them with knots made of vines, and carrying out other odd jobs, including conjuring 'Bananamana'.
Some of the differences between Tiki Towers and World of Goo can be subtle. What's the difference between a goo tower and a bamboo tower, after all? Well, a lot of the difference is in the physics engine. World of Goo is very bouncy. There you'll constantly fight gravity as your gooey structures sway left and right. Tiki Towers has gravity too, but here its effect is to challenge the stability of your structure. If too much stress is put on a piece, it can break, potentially causing other pieces to break in a cascading effect. In both games, your job is to build a stable structure, but it is the tools you have to work with that are what really set the two games apart."
