A long with some general minor changes I made quite significant changes to the difficulty settings so I thought I'd upload the changes as it affects how the game plays.

Novice is largely the same. Normal, hard and very hard now no longer give you the shades power up by default every time you take control of a new biker.

Shades protect you from 1 hit from a projectile or mine.

This makes the game more dependant on skill and less forgiving.

Normal difficulty is harder as a result, however, both Hard and Very Hard have been toned down significantly to compensate.

I gave the off screen targeted shots in lvl 1 a bit of a run up as well so as long as you aren't just staying still you are less likely to be snipered when near the top of the screen.

As before, Normal is my comfort zone. Hard is pitch to how well I can play if I'm trying my hardest and manage my best (and trying over and over) and very hard is beyond my current ability but feels like I could get there.
