Feedback What's a good name for my game?

I'm making a first person parkour game much like Karlson but you can only do one thing at a time, like press 1 to be able to jump, press 2 to be able to wall run but not jump, etc.. What's a good name for this? Currently I'm just calling it One at a Time but I'm not happy with that.

 

Call it just one. For me names must be simple, and explain the most. One is perfect.

O N E

(Kinda cool, doesnt it?)

 

Call it, "One Two Three Go!"

 

I abandoned this game because the overall concept just wasn't great, but I'm picking it back up simply to use that fantastic name. I've already gathered 5 hundred million from investors and god himself spoke to me telling of how this game was going to unite the world and conjure world peace. Thank you for what you've done for me.

 

Mechanic is cool, but maybe name of the game shouldn’t named by mechanic.
