there's a concept called optimal price.
You wouldn't get a 10 usd hooker, neither you will buy a 50 usd soda can.
You need to compare your game to stuff similar in quality and content.
So, a 5-15 minute game would have to be priced a similar price to a 3 minute song, which I assume is like 1-2 usd.
So, your ideal is to understand what cathegory of goods your game is.
