When I began work on the iOS version of Happy Wheels, I questioned whether or not it would be accepted into the App Store at all. I found examples of bleeding limbs, gibs, blood explosions and screams in iOS games, but no one example seemed to put all these effects together like Happy Wheels does. Also, at the time, the App Store guidelines were intentionally vague in places, "What is objectionable content? We know it when we see it." So I submitted our little game and breathed a sigh of relief when it was accepted with a 12+ age rating.
However, the App Store and its guidelines are living, breahting entities that change over time. Eventually one of our updates was reviewed by someone who felt the violence was not "cartoon/fantasy", but "realistic", requiring an age rating of 17+ (and banishment from the Brazilian App Store–Sorry, Brazil!). We didn't love this as many Happy Wheels players are below the age of 17, but we went along with it and really nothing seemed to change. Goody.
But then the App Store issued an objection which was not as easily remedied: inury to Irresponsible Dad's child. We were always a bit concerned that this might be an issue and if so, how would we work around it? We ended up going with the obvious solution which was to disable injury to the child. Before anyone throws their arms up in angry protest, I suggest you try it. The child can fall off the bike and will ragdoll, but always remains intact. If you find this lack of violence utterly offensive, let us know. We're considering an alternate solution.
Because of the aforementioned changes, it was easy to implement the option to remove blood/gore from all characters. This option can be found in the Option > Advanced Options. This was request made by a few people... very few.
With that out of the way, the update 1.0.6 also includes levels 1-5 for Wheelchair Guy.
I am actively working on the Android version. After other solutions failed, I decided to go with a pure C++ rewrite of the code. This is unfortunately the best, but slowest solution. At this point, I've got the base characters working as well as couple of the vehicles. It's a good start, but it's still a ways off. Sorry about that. I'd give a more specific timeframe, but I would be guessing and probably inaccurately.
Jim says that he'll update the blog soon.
