This was a really, technically impressive jam game. Everything you managed to squeeze in is an achievement and you should be proud of that, but it also makes it a pretty intimidating jam game. There was a lot to remember, and I ended up finding out the optimal strategy was just to stay in first person mode and patrol and take out the enemies.
It's too bad, because the third person spells are awesome and I wanted to use them more, but it was hard to tell where an enemy would come from. I know you give some telegraph animations on the gate, but maybe if you made it even more prominent with a beacon shooting up well in advance so the player has time to position and strategize.
The dragon coming to life animations are awesome. So much good in here, it's just so much all at once.
Great work. Awesome solo dev entry.
