I've spent some time the past couple of days taking a look at how the game performs across different systems. Specifically HIGHER fps systems were having inconsistent physics and I wasn't satisfied with that. So I've hit the game with the CONSISTENT PHYSICS ACROSS FRAMERATES hammer, and added some options for players to fine tune things themselves.
All users should see some minor performance improvements as well, specifically less sprite jittering when you're moving around or falling.
By default the game has vsync enabled and does not cap fps, but feel free to fiddle with the new options to see what works best for your system.
Cheers, and happy climbing!

Patch Notes:
"Cap FPS at 60" and "Vsync" buttons have been added to both options menus
You can no longer open the credits page after selecting start game
Various physics objects and timers now behave the same regardless of framerate (scarf, trail behind the player, fall timer)
Physics are now interpolated, so there should be less or no jitter of sprites at higher frame rates
