As you might already know, we are launching a new version of the designer at the end of the month. Among great features we are adding and will continue to add to the service, one big change is that we are starting to cap the free trial period.
When you log in to designer.soom.la after the new version has been deployed you will see a few changes related to that.
It will look a lot like the image below
The Export functionality will be temporarily grayed out until you select a plan. You can do that easily enough by clicking on any of the areas I marked in red. This will pop up the plan selection screen (below) in which you will also be prompted for a payment method that will be used once additional trial period is over.
The recommended program currently is the 29$ Plan. It supports Unity and Cocos2d-x and allows you 10 exports per month which should be sufficient as a starting point.
Note that once you select a plan your trial period will be extended by an additional 30 days with the features of that specific plan. Also note that the plan and the payment options can be changed later on by accessing the plan selection screen again.
