Who needs updating anyway? Ok i forgot. Well Jim Bonacci is working on Happy Wheels 2. You can check out the sneak peek of it here: Happy Wheels 2 Sneak Peek! Cool huh? That's why Jim never updated Happy Wheels 1. Because he's busy with the new game. It's unknown if it will be Here's some photos.
Anyway Happy Wheels 2 will have dynamic lighting. Jim has not added any gore yet, meaning he did not make separate body parts/pieces, or any blood. The blood will possibly look way more real and more 3D. He will possibly use the same old character voices and sound FX. If not, he will update voices and sound FX.
