That's actually a great game!
The spellcasting ability is a very nice mechanic, even though I don't think you can randomly press spells to discover them, right? I think it would have been cool if you find out a combination and activate a spell this way instead of finding it in a chest.
Apart from the spell scrolls I didn't find any other upgrades like armor or weapons. That would have been a great addition. Because in it's current form all I can really do is use magic to defeat enemies. And even though there are a bunch of mana potions, I still ran out of mana a lot.
I was also missing sound effects. I think they would have enhanced the experience a lot!
And a more minor thing is the combat log in the bottom left. If multiple things happen at the same time, like I am attacking someone and they are attacking me, I can't read both messages. Maybe just increase the number of lines shown.
But over all a great submission!
