Very good Metroidvania with a lot of super creative and interesting power ups. The pixel art was really good too, especially for the Rusalki (although the main character sprite is nothing special). Unfortunately it's brought down by having to collect power nodes which increase your damage output; this is fine on paper, but if you don't really try to find them bosses (and even regular enemies!) felt much harder than they needed to be, especially with so many of them spamming hard to dodge attacks. It's a Metroid game to play if you've run out of actual Metroid games.
