Post Jam Fixes in HTML5 version

Just want to make it clear that I've made some minor fixes to the game:

• Timer should now display properly when going into minutes.
• Holding jump should now consistently let you jump much higher than tapping.
• Jumping down certain platforms should be a lot more smoother, although you can still tap to aim downwards.

I have not changed any aspects that would effect gameplay or graphics as that would deviate the game too far from the original compo entry uploaded on Monday morning. The Windows build will not change for comparison sake.
