The game is very smooth and feels good to play! The bosses are well designed, but the player himself lacks mechanics to make the game more interesting. Rolling is way too overpowered, and you'll have to rely on it for 90% of the game.
Not somebody with a lot of experience in platformer gameplay, but I found the bosses to be rather easy to beat. I didn't lose against any bosses except for the Kraken.
Art style and animation are high quality and very sexy, but certain scenes may, uh, turn you off.
A few issues I ran into:
The Kraken fight gets laggy at times, namely the high-intensity moments. It literally slow the entire game down.
Being unable to replay the tutorial (without starting a new save) and change key options. Had to press the entire keyboard to figure out the healing key which I forgot about, turns out it was the ctrl key, lol.
P.s.: Here's a tech: jump immediately after shooting the projectile to send out a second projectile. It's risky though, because you won't be able to roll midair. Kraken best girl.
