I agree with all of this. collision needs quite a bit of work - getting stuck between walls or multiple enemies happens. I agree with needing more utility in the spells. utility will also be necessitated through a more complex world later, with enemies that actually react to you.
The game will be a much larger sequential adventure, but that does not exist yet. For now I'm happy to hear feedback about the micro level since that's all there is at the moment. Thank you for playing!
