Hey, i just realised something. at the suicide level, it DOES hint at using j to jump. If you notice when the text from the person scrolls out, it lingers on the "j" on jump.
This is an excellent game. It has it's similarities with Spore, but yet adds its own twist on it. I love the Skill Tree idea and the options on the Map/Area layout so you can choose which Map/Area you would prefer to partake in next. All in All a great game and I give it 3 thumbs up (?).
