Adding WIP Builds

Quick 'n dirty update - I've started adding unpolished WIP builds to the uploaded files, just so freshly-implemented features or overdue balancing can be experienced before it's in a more polished, proper release (if you so wish).

New stuff includes:

• Overworld
• Hint Mechanic
• Updates to Chain/combo mechanic
• Slight updates to Enemy attacks/actions
• (Currently unused) code for Enemy counter-attacks

Known issues:

• Overworld navigation wastes your time a bit
• Overworld is empty
• Impossible to tell the Shops apart
• Inn is not implemented yet
• Entering Armor Shop causes Sword Shop's "enterable" flag to be reset
