Need help

I'm working on a post LD version of my game and I'm really stuck regarding the inclusion of enemies. People who have reviewed the game both say that the inclusion of enemies helps build tension, while other say the game could do without them. What do you think? Leave a comment if you have tried the game and have an opnion on the matter. Thank you.
