You mention YuGiOh and I instantly love the game. The magic aspect and shrinking due to a shrinking potion I thought was an nice touch. I loved being small and viewing the goblets being bigger than me.
I feel as if the game could have benefited from a camera the player could control with the mouse instead a fixed camera. I had issues looking backwards. The game could have also used more checkpoints because it was demoralizing to go through all that only to fall and start way back to my checkpoint. I found a way to get back to my initial failure without a checkpoint but noticed I couldn't do that with all my failures.
