I liked this one, it stood out a bit as an endless runner too.  It gave me a few fun moments of going "I can make it!" and running through tiny gaps.
(I didn't make it)

Enjoyed playing it, simple idea but well executed. Would have liked a keyboard option as i prefer that control, but still neat idea. Maybe implement traps to discourage slowing the character down.

I could see this game as a very fun experience if you take the "exageration" and "ridiculisation" approach. Give the game some character, port to mobile platform and you are good to go. Gameplay and SFX are smouth enough, improve your style and add a lot of VFX to make the game more alive. Hope my opinion will somehow prove usefull.
