When you open GameSalad Creator and login for the first time, a free trial period begins. A day of your trial time is considered used if you use the tool for 15 minutes or more in a given day, so you can take your time and explore the product at your own pace over the course of days or weeks.
During the trial period, you may use the full functionality of the product, including publishing to all platforms GameSalad supports for testing and evaluation purposes (with the exception of HTML5 publishing; if you’d like to evaluate the HTML5 engine, use the GameSalad Arcade publish platform)
The only restriction is that all published games will include a GameSalad splash screen that indicates the game was published using a trial version of GameSalad and is not for commercial use.
