Beginning of Day 7

Yesterday was:

1. finishing projectiles/arrows
2. moving all player damage over to the bleeding/blood system rather than health/hitpoints
3. adding the "stoneskin" spell for temporary immunity from arrows (might change it to provide a damageable armour with high piercing resistance or something if I have time (which I won't) ).
4. adding the "exquisite fan" item as a projectile-based magical attack item
5. lots of little fixes and improvements

Today is the last day, so my priorities are a help/documentation pane, a title screen (mostly so there's something users obviously have to click so the internal iframe on itch gets focus for key events), balance improvements, and ideally some way to "finish" the game (like a high-mana suicide spell maybe.)
