When these type of games started appearing it was good, a nice change. But now there are so many, and they offer so little. It's dissapointing when you have a good idea like this, and at the end you even get a choice..only to find out all of them are the exact same endings.
(I'm not sure I found all the orbs though, so correct me if there's supposed to be something interesting.
Platforming wasn't frustrating since there wasn't any super-difficult jumps really, but otherwise it'd have needed improvements.
The most annoying part was getting out of the water. You can barely jump out, and when you touch the shore you get stuck for a while.
As it stands, it's ok to pass time, but nothing more.
