+added double jumping (refreshes upon bouncing off an enemy, spring, balloon, or floor)

+added coyote time. if you miss a jump, you'll get to use both your jumps to save yourself. dont forget to use flow too!

+keys indicating your rank now appear at the end of the level

• Bronze (Green): D Rank (this also includes C and B rank, but will only display D for the time being)
• Silver: A rank
• Gold: S rank
• Platinum: P rank (both S rank and all enemies saved at the same time)

+100% skin (All S rank, All enemies saved (antivirus), All enemies avoided (provirus) now has proper electric pulse coloring

I wasn't going to add these features to the SAGE branch and instead save it for the next demo, but i noticed people were struggling a bit and asking for some of these features so i decided to bring it to this branch anyway! Sorry that this doesn't address a lot of the other issues brought up. I'm still working on them and some may only be for the next demo instead of an update
