Crafty.js vs WiMi5

Easy to learn, based on Entities and Components, the later being class-like objects that entities inherit.

Has open function binding systems, allowing easy creation of custom components.

WiMi5 integrates a powerful visual scripting solution based on Blackboxes that allows you to create the logic flow of the game. You don't have to code (if you don't want) but you can also do it. WiMi5's actions and behaviors resemble flowcharts where each box represents a function or value, with connections between them representing program flow. This provides a better at-a-glance indication of game logic than a simple list of events, and makes complex behaviors easier to accomplish.

WiMi5 provides integrated back-end services, with tools available to save game session data, manage rankings, etc.

The WiMi5 platform is free to use, supported by post-publication royalties.

WiMi5 provides features to manage in-app purchases and micropayments. Virtual Goods management is integrated into the Logic Editor.

WiMi5 maintains partnerships allowing simultaneous publication to a number of Web and mobile stores, all managed through the WiMi5 platform.

Games can also be downloaded and publish it wherever you want: in your own server or with your own partners. Just check the Download feature in the settings of your game.
