Prototype 48 - Experience Points!

Prototype #48 is here and with it comes exp and levelling! Right now, the whole party shares exp and levels as a group when enough is collected, raising everyone's max HP. I have plans to make it a deeper and more interesting system in the future, but I wanted to start off simple to make sure the extra HP doesn't trivialize the king slime fight and future content.

There were also some minor tweaks to archery. The bow's charge shot no longer fires a ballistic arrow above half charge - all shots are straight shots now. In addition, a targeting reticule now appears while charging to show your shot's range. This should make the bow much easier to hit with, though I still don't feel it's as good as the melee weapons in practice yet. Expect more changes to archery in future updates.
