Very enjoyable, beautiful game
I liked the unfolding back-story, and the ohmen powers really added to the gameplay. Also the game gets a 10/10 for looks - really improved these from the last game. I do think a little something was missing. Maybe some challenge from having enemies, maybe upgrades, maybe some more story to fill in the cracks. My overall point is that I thoroughly enjoyed the gameplay, but at the end I felt sort of let down.
Perhaps the easiest and most helpful thing to add would be some more explanation/finality to the ending screen.
Still excellent piece of work.
