Steppy Pants? - https://play.google.com/store/apps/details?id=com.sgames.steppypants&hl=en

Doesn't match entirely your description but it is a 3d game that comes to mind with what you have said.
I've been enjoying Steppy Pants for the past week or so. Goes great with podcasts and things like that.
One tap gameplay, not terribly demanding and can have a nice flow sensation once you get the hang of it.
The only thing I dislike is that the "reset" time between runs can feel frustratingly long if you keep screwing up early on. Otherwise, the game is surprisingly low key.
Just make sure to either pay to disable ads or slap on airplane mode, they are pretty obnoxious.
Stephen has moved on from the company to start his own one where he made Steppy Pants, so the e-mail has probably been deactivated. I'd suggest e-mailing their official support e-mail instead.
I have this game on my phone. Android link.
