Thank you for your feedback! I did a poor job conveying where you're meant to target in the first boss fight - you're meant to destroy the consoles as well as the orbs on either side of the arena. My intent is, when I return to work on this project after Violet Witch Trials, I'll fix up the first boss so what you need to do is clearer.
I was having difficulties implementing some of the special effects of most spells - lightning is actually the only spell which currently has its unique effect as a result (an AOE around the player). In future releases, my plan is to incorporate each spell's special effects in addition to damage.
I may have something planned to break the silence during scenes... we'll just have to see! I understand they're a touch awkward at the moment.
