Without instructions on how to actually play the game, it makes it difficult to get started.
After figuring out, the i, o and c buttons are so far out of one another that it's frustrating to navigate through the menu when not in the fight.
@sniffaLussnus: You are absolutely right that the information was in "How to play" which I obviously missed. The keys are still quite far outside of one another to use during a fight (i, then return or o to select).
