Ocean Tower is a tower simulation game.
The goal is to build your tower as high and low as possible. The tower that you control can have new levels built on the upper and lower parts of the tower creating a dual strategy.
In each level you have to monitor power levels and commerce to make money. You can purchase different shops in Ocean Tower for food and entertainment that will generate revenue so you can keep building. The higher you go, the more expensive shops and levels become. Upgrading the core recycling center is important as well because it help power the entire tower.
While Ocean Tower is a simple simulation game, it can get very addictive because it continues running in the background with a timer. You can stop playing Ocean Tower for a day and come back to lots of trash, but lots of money.
It is not the most complicated tower simulation, but Ocean Tower provides a good amount of fun.
