Loved it!
This was a really charming little adventure. Lovable characters, a funny story and really entertaining gameplay.
But damn, that's what I call a difficulty spike. After the tutorial, there is no turning back. You will die multiple times. Dodging these cannonballs isn't as easy as it first seems, and the lack of invincibility-frames increases the difficulty even more. But trust me, in the end it's all worth it, because the final boss is pretty great. XD
I also experienced some minor glitches. Sometimes the wrong level was loaded and in level 4 the enemies kept breaking the collision (swimming through isles and out of bounds).
But all in all, this was a really fun game and is definitely worth playing.
Oh! This one I could get lost playing for hours....
