Pro Plugin based
The community can develop and release their own plugins to add additional features making game development easier. All of these plugins can be easily downloaded in the app.

It's got a scene-editor, cubic-model creator, text-editor, 2D image / animation importer, and a very useful tile-map editor.
Pro Easy to use programming language
Games can be published to the web with good performance, and the game-framework utilizes TypeScript to make programming games a little bit nicer.
Cons
Con You need the full game
This is an engine swap, you need the original game for the textures and other assets.
Con Not frequently updated
Although it's got very nice features as is, and the team does respond to issues at a pretty good rate, the engine itself takes a little while to get updates. It's a 3-4 person team, and they need to work jobs on the side in order to bring in income.
Even though the updates come out a little slower than other engines, the team is still very much committed to the project and still support it well.
