[Genome] Humble Beginnings

Hello. Welcome to Genome. Before we can begin, we need to determine something very, very important. Namely, what sense will our… Protagonist, start with? Oh, apologies. Getting ahead of myself there. You see, right now our protagonist is an incredibly simple organism, having no senses of its own. No sight, no hearing, no feeling, absolutely no senses to perceive the outside world. Now, although we *could* attempt to experience an adventure through the, well… Hang on..
Eyes? No, it has no eyes. Also no ears. Or taste or smell or… Hmm.
Nevermind, such an adventure would likely consist of posting the same blank icon up there followed by dot dot dot. And repeating for the duration of the adventure. So to avoid a joke that wore out its presence before it even stepped on stage, please choose a sense. This first sense is very important, and will form a major part of who our protagonist becomes, and what form this adventure takes.
