Game Physics Update and Butler Upload

Version 1(.1 butler uploaded this as Version 1 even though the first file was already on here, but any future updates will follow its naming scheme)

I updated portions of the player's physics to provide better stability on devices that push varying framerates. I tried to keep the feel of the character as similar as possible to the original, though there are some slight alterations due to the changes. 

I also decided to start using Itch.io's Butler file upload manager, which after the initial setup has made things much smoother for updates. This update will be referred to as Version 1 however, simply because it was the first one from Butler.
