You got this far into writing a game...why would you ever make double tapping A/D be jump? It's like some kind of weird Andy Kaufman prank on your desired audience.
You have to be some kind of madman to make a game in straight C. The controls being what they are is kind of fitting. I mean, it might be a prank, but like QWOP and Getting Over It, I think it's just the product of a certain kind of mind. I'm not going to be able to finish this, but I admire the craft of it.

....why? A significant chunk of commercial games released were done in C (maybe not 'straight", as they might plug into Lua or Python); and probably the majority of open source games were.
C is fairly straightforward to develop games in, and is one of the realms it excels in; so I have no idea why you'd feel this way.
I don't get your latter point either. Both Lua and Python's (the two most common scripting interfaces) native interface is in C. There's no reason they would plug into C++ any better.
