I think this game would benefit greatly from slowly introducing mechanics, and interspersing them with gameplay. The tutorial dump at the beginning is very intense and long. Remember, most gamers (myself included) are horrible ADD monsters. A nice gaming experience would be something like, learn one single thing, and then be able to play with it for a few minutes and master it. Then learn another thing. Etc...
The look of the game is great tho, I like the simple style.
