Man, this is the best game I've played so far. I beat it with about 4 deaths and trying not to die more was a really cool challenge. The only drawback is that I'm not sure if it fits the theme that well. I mean the only connection to "power" is the background story.
The mechanic is just amazing, I loved how my brain was reacting to the desired positions almost automatically while I'd played only for a couple of minutes at that point. Can't remember the last time I felt like I was learning a new game skill in such a fluent and engaging way. +The shake effect, the particle effect, the sounds and music made it feel really impactful. Definitely had a blast with the game.
Was a bit confused with how the number of health points changes after death. First you have 1, then 2, next about 7, feels like a strange progression but I didn't mind it.
