I'm so happy you liked it! Honestly it feels surreal that you and other players like what I made. Thank you for sharing that with me, it really means a lot - really.
And I'm THRILLED you went with the Wizards + Scholars build :D I did that over the weekend and it's so fun. I might need to rebalance it a bit because somebody pointed out that the Wizards scaling is too powerful with the Arcane Covenant prestige upgrade, but right now it's very fun.
As for the fireworks at the end - that's the plan! I just really wanted to show a cutscene with the Bad Wizard at the end of the demo and initially there were fireworks but it didn't look too good with the Bad Wizard cutscene and everything... But in general - YES, there will be more fireworks spectacles in the full release! :)
