Happy Wheels Sequel, commonly referred to as Happy Wheels 2, is the sequel to Happy Wheels that is currently in production. Jim Bonacci has stated that, unlike the original game, the player will be required to download the game. He has also stated it will cost around $5 - $10 to create levels, although nothing has been confirmed. Rather than Flash, the game is being programmed in C++ and uses OpenGL for rendering. As shown on Jim's Youtube channel, the new game will utilize normal mapping to fake a 3D perspective. The game will be presented in 2.5D (3D on a side-scrolling perspective).
By utilizing the capabilities of C++ and OpenGL, the sequel displays better physics, dynamic lighting, as well as normal and specular mapping to textures. This also allows the game to be more stable than its Flash-based counterpart.
Jim also said that characters will have sequenced animations in his post, "I EXIST".
