This is a very creative mechanic, very fun. When I was the shadow, I started to feel overwhelmed by the size of the levels. It may be interesting if there is a maximum range on how far I can get from my body. The spider mechanic is very fun, and well executed. I wish the rabbit jump was a bit higher.
I also think I would have liked a different input for casting spells other than right click, as it felt a bit strange for me.
Otherwise, I really enjoyed it! Great work
