0.4.1 Physics change and more!

Major change to physics affecting how you move in the air!

This is to hopefully allow for more precise movement in the air to make *certain* jumps less frustrating.

That being said I haven't tested every level with these physics so lmk if anything seems *worse* than it usual/should be.

I also changed the design of a couple levels to hopefully remove some of the more janky and frustrating bits.

ALSO THERES NOW A RESET BUTTON THAT RESETS THE WHOLE GAME SO NO MORE FILE SCHENANIGANS

(its tab btw)

also fixed issue where the keys wouldn't reset properly and would disappear into walls, soft locking players.
