Combat is a bit on the challenging - the character's attack distance + timing makes it really hard to hit the red chargers. And the stun duration prevents counter attacks.
Graphics style is really interesting - I would have like a bit of interest in the trees leaves, so they weren't quite so flat in color.
The blue rune kept disappearing on me, and if I got close it wouldn't come back.
Enemies took took long to explode to release their goodies.
