I was pretty sure it was glitched when I couldn't move to any of the locations. (I was clicking on enemy locations without yet realizing that you can only move to destination locations.) When I figured out how to move, I *still* thought the game was badly written, because of the extreme lag.
But! I was wrong. It's a *great* little game, once you figure out how to play it. Very enjoyable!
There must be something that could help new players past the initial pain period? Maybe some sort of a "click here" marker over the clickable locations? After you complete your first run, maybe there could be a message promising that the game will get faster? (I don't want people to just assume that it isn't working, and leave without giving your game a chance. It's a very nice game.)
