Didn't finish, but this is a surprisingly good game. I thought when I first saw it, that it was gunna be another 1 star game. Delightfully surprised. Very nice. When I thought I could cheese my way through it by fast toggling blades, I learned what the essences meant XD. Great idea for a game dude.
I feel like the game would be improved if you didn't have to deal with the arbitrary purchasing bits. Why not just have challenges after challenges? The entertainment get's broken up too easily, and I personally lost interest in playing when I had to stop, and figure out what weapon I had to purchase next to do my next challenges, which could simply be avoided.
