Phaser games development framework is for making 2D HTML5 games. It uses both Canvas and WebGL renderers internally and swaps between them as needed for fast rendering on mobile and desktop both. Phaser offers access to multiple physics engines, expanding the types of games available to developers. The ease of use makes this game engine popular. Colorful adult-cartoon games and simple sex sims are often developed with Phaser, and it seems especially popular with developers who make hentai and furry games, computer game parodies, and adventure style games with simple branching content where you can affect the plot.
