I didn't quite get the mechanics. I'm able to walk, pick things up and attack the creature with abilities, but once I start to somehow change characters I control, I wasn't able to figure out how to switch between them. Some seemed to have useful abilities for combat, while others didn't. I wasn't quite sure to what extent this game was completed, so not sure if there's something missing from the game here, or if I just didn't understand the different input possibilities. 

The graphics look amazing, and the prospects of the different abilities and characters are really cool, the canons bumping along behind you is amazing!
