Demo Update v.1.022

This is the second update to the demo, following the unannounced previous one. This update largely involved adding minibosses to the spawn system, and tweaking how the boss buff system worked to accommodate them (one option given on mini-bosses, three options on main boss). Nerf across the board to boss buffs to account for the total possible to receive. Hit-Stun has been changed, with each "wave" its efficacy will reduce, and both bosses and minibosses have had their base level adjusted down. Minimum Enemy Spawn Rate increases depending on game stage. The Boss Bonus Buff has been removed, as the general boss buffs supersede it. I'll likely reinstate it attached to the Quest system. Currently the Exploration element of the game is a little underperforming, as fountain buffs probably need a buff as well. Quests will now be offered more often. Various small tweaks to weapon numbers. Doris is more likely to be home, though may need to be tweaked up. Boss Buffs are probably due for another hit with the nerf stick, but I'll see how user testing goes. There were some performance issues relating to the laser that I've fixed, but there are still a few issues in testing hitting performance more than expected in the late game, so I'll be looking at that for the next update.
