Pro Free standalone viewer app allows instant, live mobile device testing
The GameSalad Viewer is a free app available for iOS, Android and Kindle. Once installed on your mobile devices, you can deploy and test your GameSalad games live on any mobile device running the Viewer that is on the same local network as your dev computer.
This even allows Windows users to test their games on iOS devices without a Mac device and without any complicated code signing or provisioning profiles.
And, you can even take your games with you -- once loaded onto your mobile device, a history option caches recent games on your device without any connection to the dev computer.
Pro Allows you to focus on the logic rather than code
Since the user mainly uses menu options there is very little code needed to be keyed in. This makes the code very easy to read and understand.
Hence there are many help videos on youtube
Pro Extensive community of seasoned professionals for support
Extensive community of seasoned professionals in all disciplines (graphics, game design, animation, physics, music, video production, marketing, etc.) producing tutorials, videos, publishing tips, free templates and who are willing to answer forum questions and help newcomers.
Pro Powerful expression editor and functions
Allows you to create expressions on par with LUA (it's back end-language).
Pro Custom collision shapes with JSON support
Allows you to import JSON data for custom collision shapes to use with Gamesalad's implementation of Box2d physics.
Pro Easy to publish
Software prepares your app so you can just send it to Apple. All my games are reviewed with no problems.
Pro Drag and drop editor

Pro Great engine
Very quick to learn and great for making games. Community is very open and helpful.
ct.js is bundled with examples, docs, and easy to follow tutorials. Documentation and tutorials are available in a side panel on every screen.
Pro WebGL support
Starting with v1.0.0-next-1, you can now write WebGL games. WebGL support is based on Pixi.js.
Pro Tileset support
ct.js supports tiles in rooms, including collision checks and some extra editor tools, like bulk migration to a new tile layer or shifting by an exact value.
Pro Applicable to most genres
ct.js aims to be a general game engine and provides tools in making games of any genre.
Pro Good code editor
The built-in code editor comes with error checking, code completions, multiple cursors support, and other modern features.
Pro Modular approach
ct.js has a "Core" library that provides basic drawing functions, room and asset management, and mouse interactions. Any other functions are added to projects as "catmods", or simply modules. These modules can be enabled or disabled in one click, and can inject their code in different game loop stages, e.g. after drawing all the objects, leaving a room, or when a new object is created.
Con Poor editor performance
Especially when you're working on a big project.
Con No scripting language or SDK
If a needed behavior is not supplied by GameSalad, there's no way to add it.
Con Product is suffering - Lacking company leadership and no voice from corporate
Some customers are currently in a holding pattern from the lack of support and messaging from GS corporate. GS is currently unstable and developers are waiting for another update that has been going on from 2015.
No word or message from GS corporate about timeframes or deliverables.
