Might involve thinking.
It had an interesting story. I followed it pretty well I think but it was a bit boring. I mean all he really does is have a conversation with himself which would have been fine except the background was almost non-existant and the main character was almost a stick figure. So there really wasn't anything too stimulating graphic wise.
The voices were really terrible I'm afraid. I couldn't understand a word they were saying and it was just plain annoying. The speech bubbles were ok though the words got a little cramped in places.
It was a decent idea but it looks like a bit of a rushed job. Add some background, a better character and even some soft background music and it will be much better.
