I'm not sure I want to be considered yet, maybe only as a last resort, but replaying downhill snowboard made me want to attempt replicating it. I might try to make a little prototype on my own time. If anything comes of it, I'll let you know!
Although I will advise you that downhill snowboard uses a sort of 2d ragdoll by pinning the different parts of the person together, and that would be difficult to do with the sprites you've provided.

Not a programmer, but if you want to spice things up with some wacky voices, feel free to hit me up man, it'd be nice to work together again!

I'll keep that in mind, thanks! Hope all is going well :)
