Thank you for all the feedback! Very happy to see that you appreciated the lightning spell. I thought it would be fun to have a spell that required a bit more player involvement than normal, and it also made it harder to avoid hitting the knights... so players would have to change a bit their playstyle when not alone. That was one of the ways for me to make players feel the trade-off that comes with working in a team/not being alone anymore, but without having too harsh drawbacks either. For the music I must say I only chose and implemented it, didn't compose it (if you're interested, you can find many more free soundtracks on incompetech.com).
