Thanks for trying it out! Sorry, you're right that the instructions aren't very clear. I'll update the page to clarify a bit. There's one guy hidden towards the upper left of the map who'll explain your objective and what little lore there is, but he's a fair ways away from the starting point. The three skills are unlocked as you level up (done via the menu) and their icons appear towards the bottom of the screen once you have access to them.
