"This game was too easy" "Puzzles was easy" or "This game was too hard" "I don't understand how to play"..

Which one to choose?

After doing fourteen Ludum dares I still struggle with game balance. I usually aim for the game to be easy to play because players will only spend 3-5 minutes on a game before moving on. So I'm thinking that the overall scoring will be higher if the player feel like it was easy and he completed the game. But on the otherhand does an easy game mean lower overall score because the player felt the game was too easy?

What do you think? Aim for making it easy to play trough to the end in 3-5 minutes or make it really hard like a real commercial game?

Also the feed on the site also would need a way to keep popular posts floating up instead of just being a timeline of posts. Like this post and disucssion will be lost in about an hour ;)

My game is at https://ldjam.com/events/ludum-dare/47/while-true-1 btw and I did aim for it to be easy.. maybe too easy.
