After playing Half-Genie Hero I was quite hesitant to buy Seven Sirens. However, this game is a lot more similar to the first three instalments of the series. I really enjoyed it. The transformations were cool, the story and the graphics were charming. To see animated cutscenes was the icing on the cake. Definitely a game you should get on a sale if you're a fan of Metroidvanias.
A sweet, short puzzle game with a cool style. For 2 Euros it's definitively worth a try.
