This is a superb concept - trying to quickly check the values each seed would give me and work out which to use and how best to use it whilst also scrambling to avoid enemies led to a very fast and frenetic gameplay loop which I really enjoyed.
I did find it hard to aim - I struggled to turn to face enemies to cast spells without taking damage, even when enemies were slowed. I feel like WASD/Arrow keys and mouse to aim would have worked better for me, although could easily be a skill issue on my part.
