I almost played 1 hour and I didn't see the time pass. I was captivated by the gameplay. I really like the "boss fight" side that gives to monsters a real utility and interest. I made a run without using any DP (a kind of self challenge) so I'm pretty sure I missed the best part of this experience... but anyway, I enjoyed the game I played. The game is really well balanced. Whether you choose to use DP or not, the game always propose an interesting challenge that keep you right in the flow. That's honorable.
I'll not spoil anything here, and I think you'll understand what I'm talking about, but a boss really surprised me... I was afflicted...
Great game, I hope there will be a sequel. Keep it up !
PS : I noticed the easter egg of the first boss ;)
