Retro Run Update 1.2.1 - minor bug fixes

Hey all! I have some fixes for yesterday's update, special thanks to Slenderminion on Discord for pointing these out! Changes - changed two of the jumps in "The Charm" level to make it feel more smooth - changed how the secret achievement is obtained, it is no longer random Fixed - fixed an issue where sometimes the car ride levels would be stationary - fixed an issue where the "insta kill" power-up in endless car ride wouldn't be removed after the time has run out - fixed an issue where getting killed by the skull car's fireball wouldn't add to the death counter in the stats tab - fixed an issue where killing a Quadbike Duo wouldn't add to the enemies eliminated stat - corrected a spelling mistake in the stats tab - fixed an issue where the rotating blades would't reset the death counter in the stats tab
