Construct 3
Your access code will allow you to bypass the very limited "free version" and unlock the premium software features. The code will work from home as well.
- Go to editor.construct.net
- Click Free Edition (top right corner)
- Select Enter Access Code
You can use Construct 3 without making an account, but you can register yourself to be able to save your progress in the cloud. Otherwise, you'll always need to download your game file to work on it with another computer.
